This commit improves the loading speed for the home timeline (and likely
other areas of the app) by employing various techniques and changes:
- Network EOSE timeout reduced from 10 seconds down to 5 seconds
- Network EOSE does not wait on relays with broken connections
- Offload HomeModel handler event processing to separate tasks to
avoid a large backlog
- Give SubscriptionManager streamers more fine-grained EOSE signals for
local optimization
- Only wait for Ndb EOSE on the home timeline for faster loading
- Add logging with time elapsed measurements for easier identification of
loading problems

This commit takes a step back from the full local relay model by
treating NostrDB as one of the many relays streamed from, instead of the
one exclusive relay that other classes rely on.
This was done to reduce regression risk from the local relay model
migration, without discarding the migration work already done.
The full "local relay model" behavior (exclusive NDB streaming) was
hidden behind a feature flag for easy migration later on.

This commit improves NostrNetworkManager interfaces to be easier to use,
and with more options on how to read data from the Nostr network
This reduces the amount of duplicate logic in handling streams, and also
prevents possible common mistakes when using the standard subscribe method.
This fixes an issue with the mute list manager (which prompted for this
interface improvement, as the root cause is similar to other similar
issues).

This commit implements nostr network subscriptions that survive between
sessions, as well as improved handling of RelayPool opening/closing with
respect to the app lifecycle.
This prevents stale data after users swap out and back into Damus.

Previously, HomeModel could listen to all subscriptions throughout the
app, and it would handle reaction and repost counting.
Once moved to the local relay model, HomeModel no longer had access to
all subscriptions, causing those counts to disappear.
The issue was fixed by doing the counting from ThreadModel itself, which
better isolates concerns throughout the app.

This commit introduces a verification step at the relay connection
level, to help ensure notes get validated at the source and prevent
security issues associated with untrusted relays.
`RelayConnection.swift` — the source that initially handles WebSocket
messages — was analyzed, and measures were put in place to prevent
(or at least minimize) unverified nostr event data being spread
throughout the app.
The following measures were taken:
1. A note verification step was added prior to the `self.handleEvent(.nostr_event(ev))` call (which sends a Nostr response to the rest of the app for logical handling).
a. From code analysis, there is only one such call in `RelayConnection.swift`.
2. `NostrConnectionEvent`, the object that gets passed to event handlers, had its interface modified to remove the "message" case, since:
a. that could be a source of unverified nostr events.
b. it is redundant an unneeded due to the `.nostr_event` case.
c. there were no usages of it around the codebase
3. The raw websocket event handler had its label renamed to "handleUnverifiedWSEvent", to make it clear to the caller about the verification status of the data.
a. Usages of this were inspected and no significant risk was detected.
4. A new `verify` method in NdbNote was created to verify Nostr notes, and unit tests were added to confirm tampering detections around all the major fields in a Nostr note.
5. Care was taken to ensure the performance regression is as little as
possible.
It is worth noting that we will not need this once the local relay model
architecture is introduced, since that architecture ensures note
validation before it reaches the rest of the application and the user.
In other words, this is a temporary fix.
However, since the migration to that new architecture is a major
undertaking that will take some time to be completed, this fix was written
in order to address security concerns while the migration is unfinished.
This fix was written in a way that attempts to be as effective as
possible in reducing security risks without a risky and lenghty
refactor of the code that would delay the fix from being published.

Currently NostrDB does not seem to handle encryption/decryption of DMs.
Since NostrDB now controls the block parsing process and fetches note
contents directly from the database, we have to add a specific condition
that injects decrypted content directly to the ndb content parser.
This is done in conjunction with some minor refactoring to `NdbBlocks`
and associated structs, as in C those are separated between the content
string and the offsets for each block, but in Swift this is more
ergonomically represented as a standalone/self-containing object.
No changelog entry is added because the previously broken version was
never released to the public, and therefore this fix produces no
user-facing changes compared to the last released version.

This commit implements a new layer called NostrNetworkManager,
responsible for managing interactions with the Nostr network, and
providing a higher level API that is easier and more secure to use for
the layer above it.
It also integrates it with the rest of the app, by moving RelayPool and PostBox
into NostrNetworkManager, along with all their usages.

This commit removes rust-nostr dependency, and replaces the NIP-44 logic
with a new NIP-44 module based on the Swift NostrSDK implementation.
The decision to move away from rust-nostr and the Swift NostrSDK was
made for the following reasons:
1. `rust-nostr` caused the app size to double
2. We only need NIP44 functionality, and we don't need to bring
everything else
3. The Swift NostrSDK caused conflicts around the secp256k1 dependency
that is hard to address
4. The way we do things in the codebase is far different from the Swift
NostrSDK, and we optimize it for use with NostrDB. Bringing it an
outside library causes significant complexity in integration with
NostrDB, and would effectively cause the codebase to be split into
two different ways of achieving the same results. Therefore it is
cleaner if we stick to our own Nostr structures and functions and
focus on maintaining them.
However, the library CryptoSwift was added as a dependency, to bring in
ChaCha20 which is not supported by CryptoKit (CryptoKit supports the
ChaCha20-Poly1305 cipher, but NIP-44 uses ChaCha20 with HMAC-SHA256
instead)

This commit makes drafts persistent.
It does so by:
1. Converting `DraftsArtifacts` into Nostr events
2. Wrapping those Nostr events into NIP-37 notes
3. Saving those NIP-37 notes into NostrDB
4. Loading those same notes at startup
5. Unwrapping NIP-37 notes into Nostr events
6. Parsing that into `DraftsArtifacts`, loaded into DamusState
7. PostView can then load these drafts
Furthermore, a UX indicator was added to show when a draft has been
saved.
Limitations:
1. No encoding/decoding roundtrip guarantees. That would require
extensive and heavy refactoring which is out of the scope of this
commit.
2. We rely on `UserSettings` to keep track of note ids, while we do not
have Ndb query capabilities
3. No NIP-37 relay sync support has been added yet, as that adds
important privacy and sync conflict considerations which are out of
the scope of this ticket, which is ensuring people don't lose their
progress while writing notes.
4. The main use cases and scenarios have been tested. Because of (1),
there may be some small inconsistencies on the stored version of the
draft, but care was taken to keep the substantial portions of the
content intact.

This commit implements profile image cropping and optimization, as well
as a major refactor on EditPictureControl.
It now employs the following techniques:
- Users can now crop their profile pictures to fit a square aspect
ratio nicely and avoid issues with automatic resizing/cropping
- Profile images are resized to a 400px by 400px image before sending it
over the wire for better bandwidth usage
- Profile pictures are now tagged as such to the media uploaders, to
enable media optimization or special care on their end.
Integrating the cropping step was very difficult with the previous
structures, so `EditPictureControl` was heavily refactored to have
improved state handling and better testability:
1. Enums with associated values are being used to capture all of the
state in the picture selection process, as that helps ensure the
needed info in each step is there and more clearly delianeate
different steps — all at compile-time
2. The view was split into a view-model architecture, with almost all of
the view logic ported to the new view-model class, making the view
and the logic more clear to read as concerns are separated. This also
enables better testabilty
Several automated tests were added to cover EditPictureControl logic and
looks.
