Polish:

- Delete scheduled posts on logout
- presets, list grouping, drawer badge, always-on prompt, logout toast
- bech hardening, retention, live countdown
- Replace `bechToBytes()` chains at three account sites with the null-safe
  `decodePrivateKeyAsHexOrNull` / `decodePublicKeyAsHexOrNull`. A malformed
  npub no longer crashes the LogoutButton composable tree or leaves the
  logoff path half-cleaned (deleted account row but cache + scheduled
  posts still in memory).
