This PR makes sure to not show the onboarding screens
when a user is logged in with an npub as it doesn't
make sense for them to see that.

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.

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.

This commit fixes a crash that occurred when swapping between Damus and
other apps.
When Damus enters background mode, NostrDB is closed and its resources
released. When Damus re-enters foreground mode, NostrDB is reopened.
However, an issue with the transaction inheritance logic
caused a race condition where a side menu profile lookup would get an
obsolete transaction containing pointers that have been freedwhen
NostrDB was closed, causing a "use-after-free" memory error.
The issue was fixed by improving the transaction inheritance logic to
double-check if the "generation" counter (which auto increments when
Damus closes and re-opens) matches the generation marked on the
thread-specific transaction. This effectively prevents lookups from
inheriting an obsolete transaction from a previous NostrDB generation.

It was decided on a standup meeting that this feature is not important
and failing tests can be disabled.
