Six interconnected fixes to make Olm/Megolm state persist correctly
across restarts:
- Fix OlmAccount/OlmSession unpickle argument order (data, key) — was
reversed, causing INVALID_BASE64 on every restore
- Fix pickle byte encoding: pickle() returns ByteArray, not StringBuffer;
encode/decode with ISO_8859_1
- Track publishedOtkCount in SharedPreferences to avoid evicting existing
OTKs on restore (only generate MAX - published new keys)
- Delay startSync() until after uploadKeys() on fresh login to avoid
concurrent OlmAccount access (race condition causing BAD_MESSAGE_KEY_ID)
- Persist encryptedRooms to SharedPreferences so rooms stay encrypted
across restarts
- Check m.room.encryption in both state and timeline events (server
returns it in timeline for rooms where encryption was enabled early)
Also adds SAS device verification UI, DM naming improvements, and
updates state.md with full architecture and debugging notes.
