Opening the playlist switcher fired one XTREAM_REQUEST IPC + HTTPS
round-trip per Xtream playlist and only updated the UI after ALL of
them resolved. A single slow or hung portal pinned every status dot
in the menu to the misleading red 'unavailable' state for the full
tail latency (often several seconds, sometimes longer).

Four changes land together:

1. Stream results — each portal's dot updates via signal.update() the
   moment ITS request resolves, independent of the slowest one. The
   previous Promise.all wrote a single Map at the end; now the Map
   grows incrementally.

2. New 'checking' status — extends PortalStatus with a pulsing-dot
   visual so users see "we're working on it" instead of red dots
   that look like failures. Respects prefers-reduced-motion.

3. 30-second TTL cache — opening, closing, and reopening the menu
   within 30s reuses prior status results and skips the IPC entirely.
   Cache survives across menu opens but is per-component instance
   (a global cache is a possible follow-up).

4. AbortController cancellation — closing the menu (or destroying the
   component) cancels in-flight checks so a slow portal can't write
   stale results into the next round. Solves the 'rapidly open/close
   the menu and watch dots flicker' problem.

The actual IPC layer wasn't changed — the wins come purely from
streaming, caching, and not lying to the user about portal state.
