Adds a Grid/Justified toggle to the photos toolbar. Justified mode packs
tiles into Flickr-style rows scaled to the container width using each
photo's real aspect ratio (from the new /api/photos width/height, falling
back to 1:1 when missing). It composes with the virtualized renderer:
per-group materialization and the off-screen spacer height estimates are
both layout-aware. The choice persists in localStorage.

- Tiles are focusable (tabindex / role=button / aria-label) with a
:focus-visible ring; Enter opens the lightbox (or toggles in selection
mode), Space toggles selection.
- Shift-click extends the selection from the last anchor across the
timeline; the range is tracked in the selection Set so it spans
dematerialized (off-screen) groups, with visible tiles updated at once.

The photos timeline rendered every tile into the DOM and grew it
unbounded on infinite scroll, degrading on large libraries. Each
date-group is now a <section> whose grid is materialized (tiles
inserted) only while near the viewport and dematerialized (emptied,
height frozen as a spacer) once it scrolls away, driven by an
IntersectionObserver rooted on the scroll container. DOM nodes stay
bounded by a few screens regardless of library size.
- Grouping (day/month/year), infinite scroll, multi-select, video
thumbnails and fade-in are all preserved.
- Selection state and the video-thumbnail cache survive the
materialize/dematerialize cycle.
- Falls back to full rendering when IntersectionObserver is unavailable.
- Spacer heights are estimated from grid geometry and re-estimated on
resize.

Backend — Photos timeline now groups by real capture date instead of upload time. New MediaMetadataService (FileLifecycleHook) extracts EXIF DateTimeOriginal from images and container creation_time from videos (mov/mp4/mkv) via nom-exif, timezone-correct (OffsetTimeOriginal), persisting captured_at so the existing media_sort_date trigger takes over. Adds POST /admin/photos/metadata/reextract to backfill existing media. Falls back to upload date when no embedded date exists.
Frontend — premium grid cards: combined metadata line (relative date · size, owner avatar when shared), custom selection checkbox with a clear checked state, uniform full-width 4:3 thumbnail tiles independent of filename length, centered file-type icons, and a hit-test fix so checkbox/star/kebab clicks reach the controls (the decorative thumbnail no longer captures pointer events). Notification messages internationalised across all 16 locales. Broader polish: design tokens, a11y/focus-visible states, brand + PWA assets.
Chore — bump semver-compatible dependencies (cargo upgrade); add nom-exif 3.6.1.

Backend: new GET /api/photos endpoint with cursor-based pagination that
queries image/video files sorted by EXIF captured_at (falling back to
created_at), joining file_metadata for sort dates.
Frontend: dense photo grid grouped by day with lazy-loaded thumbnails,
IntersectionObserver infinite scroll, multi-select with batch
download/delete, and a full-screen lightbox with prev/next navigation,
EXIF metadata display, and download/favorite/delete toolbar.
Includes navigation wiring, CSS (with dark theme), and i18n translations
for all 9 locales.
