PortalStatusService previously did one IPC + HTTPS round-trip per call,
forcing every consumer to roll its own cache (or, more often, not).
The result: opening the homepage rendered N playlist-item components
that each fired their own check, then opening the playlist switcher
fired N more for the same portals.
Move the cache and dedup into the service:
- 30 s TTL cache keyed by `${serverUrl}|${username}|${password}`. Same
credentials = same cache entry, regardless of which playlist row
triggered it.
- In-flight dedup via Map<key, Promise<PortalStatus>>. Two callers
hitting the same portal in the same tick share one network request
instead of racing.
- New `getCachedStatus()` for sync read (used by playlist-switcher to
hydrate the UI on menu open without awaiting).
- New `clearStatusCache()` for log-out / debug flows.
Add `{ skipCache: true }` opt-out for the Xtream import dialog's
"Test Connection" button — that's a user-initiated check that must
return fresh truth, not a 30 s old cached result.
Net result: in the common flow (homepage → switcher), the switcher
opens with cached status indicators instantly. The single in-flight
dedup prevents the playlist-item ngOnInit + switcher onMenuOpened from
racing for the same portal.
Removed the component-local cache from playlist-switcher; service is
now the single source of truth.
