feat(tautulli): open Plex items in the app-global quick-look modal

CHANGELOG.md

@@ -20,7 +20,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Plex activity via Tautulli (optional).** A new read-only Tautulli integration (URL + API key in `/admin/settings`, behind the per-service health circuit breaker) surfaces current Plex activity. The dashboard gets a "Current Plex activity" widget — active streams, Direct Play / Direct Stream / Transcode counts, total / LAN / WAN bandwidth and a per-session card (quality, HDR/SDR badge, source→target codec when transcoding) — that hydrates on its own and refreshes every 10 s. A dedicated **Plex Activity** page (own sidebar entry) adds a now-playing strip, watch statistics with a 7 / 30 / 90-day toggle (top movies / shows / users / platforms), plays-over-time graphs with a Media-type ⇄ Stream-type toggle plus by-hour and by-day-of-week breakdowns and a platform × stream-type "problem clients" chart, a dense watch-history grid, and per-library item counts. Each title opens an in-app info modal (synopsis, ratings, cast/crew). The API key never leaves the server, every response is sanitised before it reaches the browser, and each section fails open independently so a down/misconfigured Tautulli never breaks the dashboard or page. Chart.js is self-hosted (`public/static/chart/`) for CSP compliance and reused by the existing Radarr stats chart.
 - **In-place quick-look on the dashboard.** Clicking any media tile — hero spotlight, upcoming, weekly trending, watchlist or latest additions — now opens a read-only detail modal right on the dashboard (poster, year, status, rating, genres, synopsis) instead of navigating away, with a deep-link to manage the item in Radarr/Sonarr or open it in Discover. Library items resolve from the already-cached dashboard aggregate (zero extra upstream calls on a warm page, falling back to a direct fetch on a miss); TMDb items resolve straight from TMDb. The fragment is read-only and fails open to a small graceful body, and the modal is Turbo-safe (declarative trigger, escaped values).
 - **Plex Activity page — statistics, graphs & a per-user filter.** The activity page's statistics gain Most Popular Movies / Shows tiles (ranked by distinct viewers), a Most Concurrent Streams tile, and a **Play Count ⇄ Play Duration** toggle that reformats every count-based tile and chart into watch time. Four new graphs are added — plays by source resolution, plays by stream resolution, streams by user, and concurrent streams over time (always a count, never reformatted as duration) — alongside a new privacy-safe **Users** overview table (friendly name, relative last-seen, last played, play count, total watch time). A page-wide **per-user filter** dropdown scopes the statistics, all graphs and the history grid to a single user, or all users (the Users overview table always lists everyone). The metric and user-id are clamped/validated server-side (`metric` ∈ `plays|duration`, user filter digits-only), every new client method and endpoint fails open to its neutral shape, and the allow-list keeps email / IP / avatar / Plex login off the wire — the opaque Tautulli user-id is a filter token only and never rendered. All data comes from read-only Tautulli commands (`get_home_stats`, `get_users_table`, `get_user_names`, `get_plays_by_*`, `get_concurrent_streams_by_stream_type`); strings are i18n'd (en/fr).
+- **Rich detail modal from top-bar search, with release dates.** Clicking a search result now opens the quick-look detail modal (instead of jumping straight to the quick-add form), enriched with release/air dates: movies show theater / digital / physical dates (the next upcoming one emphasised), TV shows a Continuing/Ended status with first-aired and next-episode (or end) dates. The action button is context-aware — **Manage** (deep-link) for items already in your library, **Add** (the existing quick-add flow) for ones that aren't. In-library results use the authoritative Radarr/Sonarr dates; not-yet-added results read from TMDb (theater/digital/physical parsed from TMDb's `release_dates`, FR→US fallback; series air dates from `next/last_episode_to_air`). The quick-look modal is now app-global (extracted to a shared partial), so it's available from search on every page and the dashboard tiles reuse it. Labels are i18n'd (en/fr); the modal stays read-only and fails open.
 ### Changed
+- **Plex items open the app-global quick-look modal.** Clicking a title on the Plex Activity page or the dashboard's Plex widget now opens the same rich detail modal used everywhere else (poster, synopsis, ratings, watchlist button, Manage/Discover deep-links) instead of the bespoke Tautulli metadata pop-up. The click resolves the item's TMDb id server-side (`/tautulli/api/quicklook/{ratingKey}`, one `get_metadata` call — episodes/seasons resolve to their show, with a grandparent hop for older Tautulli payloads that lack show-level guids); only the numeric TMDb id reaches the browser, keeping raw Plex guids inside the existing allow-list sanitization. Items with no TMDb match (music, home videos) fall back to the legacy Plex metadata modal, so every click keeps working.
 - **Dashboard service-health chips show latency.** `HealthService::statusFor()` returns a status word plus a round-trip reading (cached 10 s like the existing bool path, which now delegates to it); the dashboard chips render five states — up / slow / very_slow / down / degraded — with a coloured dot, so a reachable-but-slow service is visibly distinct from a healthy one. `isHealthy()` keeps its old contract for every existing caller.
