feat: add blockchain explorer settings page for OTS verification

Adds a new "Bitcoin Explorer (OTS)" settings page in App Settings,
modeled after the existing Namecoin settings page.

Users can configure a custom Mempool-compatible blockchain explorer
API URL for OpenTimestamps proof verification. When a custom URL is
set it takes priority over the automatic Tor-aware selection (mempool.space
when Tor is active, blockstream.info otherwise).

Changes:
- OtsSettings: immutable data class for explorer config
- OtsSharedPreferences: DataStore-backed persistence (global/app-level)
- TorAwareOkHttpOtsResolverBuilder: accepts customExplorerUrl lambda
- OtsSettingsSection: UI section with active explorer display, URL input,
  known-explorers reference list, and reset button
- OtsSettingsScreen: full screen wrapping the section
- Routes.OtsSettings: new navigation route
- AllSettingsScreen: new entry under App Settings
- AppModules: wires otsPrefs and passes custom URL to resolver builder
