Fixes reported by testers and found in an app review: - First message right after install no longer fails. Before the app finished registering with the relay, the outgoing message could crash on a null delivery address. The profile field is now optional and the send path throws a clear "still connecting, try again shortly" error while registration completes in the background. - The QR code and share link now appear only once the delivery address is ready. Previously a link generated before the first connection lacked routing, so the other side could not send the first message. The screen now shows a connecting state and reactively swaps in the QR when ready. - Incomplete contact links are rejected on import instead of failing at first send, with a clear prompt to ask for a fresh link. - Auto-lock no longer silences the app: after locking and unlocking, messaging is restarted (it previously stayed dead until app restart). - Group messages are marked failed on a non-per-member send error instead of hanging in the "sending" state forever. - Hardened the relay client against a rare duplicate connection when toggling Tor or locking mid-connect, and fromShareString now rejects a delivery address of the wrong length. - Pin unifiedpush below 6.2.0 to drop the webcrypto dependency (its native framework lacks LC_ENCRYPTION_INFO and blocked the iOS upload). - Skip Android release lint (network dependency check hangs on the build host and adds no value for a Flutter app).
