This commit adds a new event subscription task in HomeModel, one which
streams low volume but important filters from NostrDB.
This was done to address an issue where the contact filters in the
general handler task could yield too many notes from NostrDB, hitting
its limits and clipping off important events such as mute-lists, leading
to downstream issues such as unintended mute-list overrides.
This issue was not present since the last public release, therefore no
changelog entry is needed.

It was noticed that occasionally the profile name at the event view
would not load to the user's display name.
The issue was fixed by adding a missing profile observer.
Issue introduced after our last public release, no need for changelog
entries.

Previously, the note content rendering logic would wait for the note
and its blocks to be available in NostrDB before displaying the parsed
version of the note to the user.
However, it is now possible to parse those on demand, and there are code
paths to ensure that it will do so if those parsed blocks are not
readily available from NostrDB.
Therefore, the wait is not necessary, and removing it fixes the delay we
have been experiencing.
The issue was likely introduced after the last public release, so no
changelog item is needed

This PR adds the new Damus Labs view.
This will allow us to make the new things we work on more prominent.
Any new features we want to iterate fast on and get to our users a lot faster
are perfect for Damus Labs. This will be exclusive to Damus Purple Subscribers.

A race condition was identified where notes would get dropped if they
get indexed in the time window between when a query is made and the subscription is made.
The issue was fixed by making the subscribe call before making the query
call, to ensure we get all notes from that time when we perform the
query.
This dropped the failure rate for ndb subscription tests from about 20%
down to about 4%.
Local relay model issue was not publicly released, which is why the
changelog entry is "none".

This attempts to reduce race conditions coming from Ndb streaming
functions that could lead to lost notes or crashes.
It does so by making two improvements:
1. Instead of callbacks, now the callback handler uses async streams,
which reduces the chances of a callback being called before the last
item was processed by the consumer.
2. The callback handler will now queue up received notes if there are
no listeners yet. This is helpful because we need to issue the
subscribe call to nostrdb before getting the subscription id and
setting up a listener, but in between that time nostrdb may still
send notes which would effectively get dropped without this queuing
mechanism.

This fixes a hang during sign-up, which was caused by a change in
RelayPool handling code that would only send data to handlers with
matching subscription IDs.
It so happens that some handlers want to receive all notes, and they set
the filters to `nil` to achieve that.
Furthermore, some sign-up networking code was moved to prevent race conditions.
No changelog entry because the behaviour was not changed since the last
public release.

This is a large refactor that aims to improve performance by offloading
RelayPool computations into a separate actor outside the main thread.
This should reduce congestion on the main thread and thus improve UI
performance.
Also, the internal subscription callback mechanism was changed to use
AsyncStreams to prevent race conditions newly found in that area of the
code.

Changelog-Removed: Removed "Load new content" button

This improves upon a temporary fix we had for the RelayPool race
condition that would cause timeline staleness.
The root cause was that during app launch, the HomeModel would subscribe
to some filters, and the subscribe function would filter out any relays
not yet connected to avoid unnecessary waiting for EOSEs from disconnected relays.
However, that filtering would cause the subscribe request to not be
queued up or sent back to the relays once connected, causing the relays
to never receive those subscription requests and causing timeline
staleness.
This was fixed by separating the relay list used for the subcription
request from the relay list used for waiting for network EOSEs. This
allows other mechanisms to ensure the subscription will go through even
when the app is initializing and relays are not yet fully connected.

Previously, we combined the ndb and network stream within a "session
subscription" stream, which was teared down and rebuilt every time the
app went into the background and back to the foreground (This was done to
prevent crashes related to access to Ndb memory when Ndb is closed).
However, this caused complications and instability on the network
stream, leading to timeline staleness.
To address this, the pipeline was modified to merge the ndb and network
streams further upstream, on the multi-session stage, allowing the
session subscription streams to be completely split between Ndb and the
network.
For the ndb stream, we still tear it down and bring it up along the app
foreground state, to prevent memory crashes. However, the network stream
is kept intact between sessions, since RelayPool will now automatically
handle resubscription on websocket reconnection. This prevents
complexity and potential race conditions that could lead to timeline
staleness.

- Resend subscription requests to relays when websocket connection is
re-established
- More safeguard checks on whether Ndb is opened before accessing its
memory
- Cancel queued unsubscribe requests on app backgrounding to avoid race
conditions with subscribe requests when app enters the foreground
- Call Ndb re-open when Damus is active (not only on active notify), as
experimentally there have been instances where active notify code has
not been run. The operation is idempotent, so there should be no risk
of it being called twice.

This commit adds more safeguards to prevent RUNNINGBOARD 0xdead10cc
crashes, by:
1. Using the `beginBackgroundTask(withName:expirationHandler:)` to
request additional background execution time before completely
suspending the app. See https://developer.apple.com/documentation/xcode/sigkill
2. Reorganizing app closing/cleanup tasks to be done in parallel when
possible to decrease time needed to cleanup resources.
