feat(xtream): resume the latest series episode (#1187)

Dashboard Continue Watching now carries the exact saved season/episode into
Xtream series details and starts it at the persisted offset. Successful
external MPV/VLC launches persist the launched episode and retarget the
series CTA to "Play episode N". Recent-history rows keyed by an episode id
resolve their parent series before navigation.

Includes maintainer follow-ups: no zero-offset resume on failed position
loads, seriesXtreamId-gated resume targets for legacy rows, and patch
coverage raised from 76.7% to 93.9%.

 - Xtream and Stalker detail pages use the shared `PortalDetailShellComponent` (`libs/ui/components/src/lib/portal-detail-shell/`) with two states: **Browse** (hero with poster/metadata/actions, episodes below) and **Watch** (hero collapses with a ~300ms morph, the inline player takes the full content width, metadata moves to an About block below the episodes)
 - Watch state derives from `inlinePlayback() !== null` only; external MPV/VLC playback keeps the browse layout. Esc and "Close player" exit to browse without navigation; the now-playing back arrow is route-level back (straight to the list via the host's `goBack()`)
+- A successful external MPV/VLC episode launch immediately persists the selected episode as the latest playback-position entry and retargets the series CTA to `Play episode N`; real player telemetry overwrites that marker when available, so episode identity is reliable while exact external timestamps remain best-effort.
 - Hosts pass hero chips/meta/actions as `*appDetailTags`/`*appDetailMeta`/`*appDetailActions` templates; the shell stamps them into both the hero and the About block
 - Seasons are tabs (`SeasonTabsComponent`, dropdown beyond 6 seasons) with auto-selection (playing episode's season → resume season → first) that fires the same `seasonSelected` lazy-load/enrichment hooks as manual clicks; grid/list episode view toggle persists to localStorage; season descriptions come from `get_series_info` (Xtream) or TMDB (Stalker)
+- Dashboard hero/Continue Watching clicks for an Xtream series carry a one-shot resume target through the global-recent inline-detail handoff; after series metadata and playback positions load, the exact saved episode starts at its stored position. A failed positions load leaves the target unconsumed and the handoff detail-only, so a transient storage error never starts the episode from the beginning. Ordinary global-recent grid clicks remain detail-only.

 The detail or collection/search host owns inline state. `PlayerService` is not
 an owner of embedded UI playback state.
 
+After a successful external episode launch, the detail host immediately
+persists that episode as the latest playback-position entry, preserving an
+existing resume offset or using zero for a newly opened episode. MPV/VLC
+position telemetry overwrites this launch marker when available. This keeps the
+last-watched season and episode correct even when an external player's progress
+interface is unavailable; exact external timestamps remain best-effort.
