feat(desktop): wire Import Follow List dialog into UI

The ImportFollowListDialog composable was already implemented but never
rendered. The File menu item set a boolean state that no observer
consumed.

Render the dialog from MainContent inside the CompositionLocalProvider
that supplies LocalNamecoinService, so Namecoin (.bit, d/, id/)
identifier resolution works in addition to npub/hex/NIP-05.

Also add a left-side launcher in both layouts so the feature is
discoverable without using the File menu:
- single-pane: NavigationRailItem (PersonAdd icon, 'Import' label)
- deck: IconButton in the DeckSidebar next to 'Add Column'
