feat(web): native favorites, lightbox zoom, EXIF jump links + perf fix

- Favorites use PhotoPrism's own like/unlike endpoint (not a mule-only mark) so they sync to third-party gallery apps, with heart controls in the tile, sidebar, and an `f` shortcut. - Lightbox: wheel-zoom around cursor, double-click to 2.5x, drag-to-pan, auto-upgrades to the fit_2048 tile past 1.25x zoom. - Sidebar: copy-EXIF button, clickable Camera/Lens values that jump to a filtered timeline (camera:/lens: DSL), matching the existing Country link. - Fix filtersToQ() quoting the entire search string whenever it contained a colon, which silently turned any raw DSL operator (camera:, taken:2024, etc.) into a literal phrase search — discovered while verifying the new jump-links against production. - Disable TanStack Query's refetchOnWindowFocus: the indexer WebSocket already invalidates photo queries on real changes, so the focus refetch was just a redundant full-timeline re-render on tab-switch.
