This commit adds Damus Purple expiry notification support.
How it works: Whenever the app initiates or enters the foreground, it
checks the user's account expiry, and calculates what notifications to
display (It is functional, not imperative, to better match how
the notifications view works)
The notification handlers work the same as every other notification
handler for Nostr events. However, local iOS notifications were not
implemented to maintain these reminders more discreet.
Current limitations:
- Notifications cannot be dismissed
- Notifications are dismissed only when Damus Purple is extended
- After making a purchase, notifications are not dismissed right away
- Bell icon with purple badge shows up on every app restart if user's account is expired

Setup:
- Local servers Setup
- Debug endpoints enabled for changing expiry date on the fly
Coverage:
1. Expired account
1. Starting the app on home screen shows bell icon with purple badge. PASS
2. 4 notifications appear on notifications view (7,3,1,0 days to expiry). PASS
3. Notifications appear in correct chronological order. PASS
4. Notifications look consistent in appearance. PASS
5. Expiry notifications' text size follows text size settings. PASS
6. Clicking on notification CTA takes user to account info page. PASS
2. Non-expired account (set expiry, restart app)
1. No expiry notifications, no bell icon. PASS
3. Expiry in 6 days (set expiry, restart app)
1. Starting the app on home screen shows bell icon with purple badge. PASS
2. Starting the app on the notification screen renders notifications the same way. PASS
3. Only one notification (7 days remaining) appears. PASS
4. Expiry in 2 days. PASS
5. General
1. Clicking bell icon clears away "new notifications" badge. PASS
2. Performance of notifications view does not seem affected. PASS
3. Performance of app on startup does not seem affected. PASS
6. IAP
1. Active IAP + expiry date in 2 days does not trigger reminder notification (Because it is auto-renewed). PASS

Changelog-Added: Notification reminders for Damus Purple impending expiration

This commit brings key local notification logic into the notification
extension target to allow the extension to reuse much of the
functionality surrounding the processing and formatting of
notifications. More specifically, the functions
`process_local_notification` and `create_local_notification` were
brought into the extension target.
This will enable us to reuse much of the pre-existing notification logic
(and avoid having to reimplement all of that)
However, those functions had high dependencies on other parts of the
code, so significant refactorings were needed to make this happen:
- `create_local_notification` and `process_local_notification` had its
function signatures changed to avoid the need to `DamusState` (which
pulls too many other dependecies)
- Other necessary dependencies, such as `Profiles`, `UserSettingsStore`
had to be pulled into the extension target. Subsequently,
sub-dependencies of those items had to be pulled in as well
- In several cases, files were split to avoid pulling too many
dependencies (e.g. Some Model files depended on some functions in View
files, so in those cases I moved those functions into their own
separate file to avoid pulling in view logic into the extension
target)
- Notification processing logic was changed a bit to remove dependency
on `EventCache` in favor of using ndb directly (As instructed in a
TODO comment in EventCache, and because EventCache has too many other
dependencies)
tldr: A LOT of things were moved around, a bit of logic was changed
around local notifications to avoid using `EventCache`, but otherwise
this commit is meant to be a no-op without any new features or
user-facing functional changes.

Damus: This commit
Coverage:
1. Ran unit tests to check for regressions (none detected)
2. Launched the app and navigated around and did some interactions to
perform a quick functional smoke test (no regressions found)
3. Sent a few push notifications to check they still work as expected (PASS)
