#376 feat(badge): read unread and mute state from Messenger's database

[Anonymous]

Originally created by: kristofferR

The unread badge guessed which chats are unread from bold text, and which are muted from localized labels in eight languages, an icon fingerprint and pixel offsets. Those guesses break on new locales, theme or markup changes.

Messenger's local database already holds the facts the list renders: MWPIsThreadUnread.isThreadUnreadForViewer decides a chat's "Unread message:" label, and muteExpireTimeMs says whether it is muted (-1 forever, or a future time). The badge now reads both for the listed chats and prefers them. The rendering heuristics stay as the fallback for any chat the database can't answer for, and a diagnostics line notes when the database is unavailable. Database mute state also feeds the shared muted-thread store that notifications use.

Reads are asynchronous, so the count uses the latest snapshot and re-applies when a refresh changes it. Unanswered or failed reads drop their cached entries so rendered evidence takes over again, and an explicit mute or unmute outranks database reads for a few seconds while Messenger writes the change.

Idea from fMess (MIT).

Manual check still needed: badge count across languages and with chats below the fold; mute for an hour, mute forever and unmute; Carrier.log should not show badge.thread-state.
