feat(dashboard): say where you left off instead of which provider it came from (#1646)

Every dashboard title carried a "Xtream · Series" / "Stalker · Movie" subtitle. Provider kind and content kind are the app's own taxonomy, not a property of the title, and they are identical on every card in a rail — so the one line that could tell two cards apart said nothing.

The hero now shows the source name alone, through `playlistDisplayLabel` (a stored playlist name is routinely the pasted URL with credentials, or a MAC). Continue Watching cards show what actually varies: the "S1·E5" chip plus "12 min left". Favorites keep the title alone, Recently Added keeps the source name, and a meta row with nothing in it is no longer rendered.

Stalker shows filed under Movies had no badge, no progress and no resume. An embedded-VOD row announces its episodes through a `series[]` array and carries no `is_series` flag, so `extractStalkerItemType` reports `movie` on purpose — the item must keep routing to the VOD catalog — while its progress is a set of episode positions keyed by the parent id, which the dashboard was looking up as a single `vod` row and never finding.

Split the two questions: `PortalActivityItem.watch_kind` records the progress model when it differs from the routing type, and every reader that has to choose goes through `resolvePortalActivityWatchKind` instead of `type`. That makes the resume handoff reachable for Stalker, so wire it through `STALKER_SERIES_RESUME_TARGET`: consumed once after the series positions are read, hydrating a lazy Ministra season first with a bounded two-attempt retry, and playing nothing at all when the position read failed rather than restarting the episode from zero.

Also fixes the global-recent route template, which bound `[seriesResume]` only on its Xtream branch.

+The dashboard no longer labels every title with "Xtream · Series" or "Stalker · Movie": the hero shows only the source name, and Continue Watching cards show the episode you are on plus the minutes left. Stalker shows filed under Movies now get that S·E badge, the progress bar, and a working "Resume episode" that opens the show at the saved episode.
