05150c1188 feat(mobile): sync themes per community (#3767)
**Category:** new-feature
**User Impact:** Mobile now keeps each community’s appearance in sync
with desktop, including theme, accent, and system-mode preference.

**Problem:** Appearance choices were device-local, so the same account
could look different between desktop and mobile. Live sync could also
stop after the relay closed a subscription.

**Solution:** Store each community’s encrypted appearance preference on
its relay using the shared desktop wire contract, restore it from a
local identity-scoped cache, and apply replacement events live. Closed
subscriptions now recover with guarded backoff and fetch the latest
preference so no update is lost during the gap.

## Reproduction steps

1. Sign into desktop and mobile with the same account and join the same
community relay.
2. On desktop, choose a distinctive non-Buzz theme and accent; mobile
should update without a local toggle.
3. Restart mobile and confirm it restores the same appearance.
4. Change the mobile theme and accent and confirm desktop follows.
5. Leave mobile idle or backgrounded through a relay reconnect, then
change desktop again; mobile should resubscribe and catch up
automatically.
6. Switch communities and confirm each community restores only its own
appearance.
