feat(settings): quick wins from the settings audit (#453)

- #456 Copy pass: sentence case for every setting title and section,
  plainer names ("Hide joins and leaves", "Link previews", "Emoji
  style: Twemoji", "Rejoin calls after a restart", "Also use the
  browser's noise suppression", "Push-to-talk key"...) and grammar fixes
  ("when messages arrive", "Play a sound when a new message arrives",
  blocked users "Enter their Matrix ID"). Labels only: no setting is
  renamed in storage.
- #455 One theme control: Theme: System / Light / Dark. System shows the
  light and dark variant pickers, Light or Dark one picker of that kind.
  Replaces the System switch plus a Theme dropdown that was greyed out
  whenever the switch was on. Uses the existing settings (no migration);
  picking a variant also remembers it for System.
- #457 Remove the "Block Messages" stub from Notifications; the GIF
  picker row only appears in builds with a GIF key.
- #458 (part 1) "Export/Import Messages Data" -> "Export/Import
  encryption keys", with a sentence on when you need it.
