Save theme + Runes to the repo, show “Preferences saved” after upload,
and pull newer prefs on focus/poll for cross-device updates. Add native
persisted onUpdate + onPostWrite hooks.

social-app upstream seems to have bumped its SDK

Additionally, environment variable handling has been improved to avoid
impurities in the flake.

Verified by doing:

```sh
export NODE_ENV=production
yarn prebuild -p android && (cd ./android && ./gradlew assembleRelease)
```

I heard it's common etiquette. Nevertheless, it is disabled by default
to avoid surprising users.

Fixes #98. Tested locally.

Default moderation settings are still applied to logged-out accounts
(per comments in the file, logged-out moderation settings are now
downstream of AA code, ~~because bsky pbc are jerks like that~~ because
it makes sense to keep everything in one place), but logged-in users are
now afforded the freedom to choose their own moderation settings, as
intended.

I did not touch logged-out moderation prefs to avoid exposing users who
might not yet have access to the moderation panel due to not having an
account to anything objectionable — this, in my opinion, is sufficient
balance considering AA is no longer functional for logged-in users.
