fix: briefing refresh — weather not populated + workspace conv bleed

Two bugs:

1. Manual 'Refresh' button didn't refresh weather/RSS before compiling.
   The daily scheduler calls refresh_all_feeds + refresh_location_cache
   before run_compilation; the manual trigger route called run_compilation
   directly, reading a stale cache. Manual trigger now mirrors the
   scheduler: refresh feeds and all configured weather locations first.

2. Navigating to WorkspaceView during a long briefing compilation caused
   the workspace chat to show the briefing content. triggerNow awaits
   ~30-60s; on completion it called loadAll() → chatStore.fetchConversation
   which overwrote the workspace's currentConversation in the shared store.
   Fixed with a _mounted flag — all post-async state writes in BriefingView
   are now guarded so they no-op if the component has been unmounted.
