feat: activate anonymous reply by tapping user picture instead of bottom button

Replace the bottom bar AnonymousPostButton with a tap-on-avatar activation scheme.
Tapping the user picture enables anonymous mode and shows the incognito icon in its
place. Tapping the incognito icon toggles back to normal mode.
