fix: Launcher dead-code cleanup — dead else-if branch and unused handle_get_device_info

- launcher/+layout.svelte: dead {:else if $events_slct.event_session_id} branch
  (condition identical to preceding {#if}) replaced with correct
  {:else if $events_slct.event_location_id} — shows "Select a session"
  prompt when a room is chosen but no session is yet selected.

- launcher/[event_location_id]/+page.svelte: removed unreachable
  handle_get_device_info() function (never called; pre-relay pattern
  superseded by launcher_background_sync.svelte's run_device_heartbeat()).
  Cleaned up now-unused imports.
