feat(tui-v2): add dedicated Settings Board inspector view

Replaced the 'Settings' shortcut palette pre-fill with a real inspector
board. Added #settings-board widget and settings pane mode. Implemented
_refresh_settings_board to show live config values and palette hints for
Security, Backup, and Nostr settings. Updated interactive agent test to
verify settings board activation via action strip click.
