- Context menus (PopupMenu, Nearby/QuickMsg call sites) go back to centring on
screen; the header's discoverable-menu glyph stays, but dropping the popup
out of its corner looked bad on some screens.
- Unread pill badge digit wasn't centred: Adafruit_GFX's classic built-in font
(SH1106/SSD1306) always pads a measured string by one trailing advance
column regardless of the glyph drawn, so centring on the raw width left 1px
more slack on the right than the left. New DisplayDriver::
textWidthTrailingGap() (0 by default) corrects for it on those two backends.
- On-device room Logout: mirrors the app's CMD_LOGOUT (drops keep-alive
tracking, forgets the saved password) so a room can be deliberately signed
out of from the Room options menu, not just re-logged-in.
