George Cushen bdd3820f27 feat(gallery): sidecar files, EXIF/IPTC, and page-bundle auto-discovery ...

Adds the metadata pipeline that makes the gallery block self-curating.
Per-image metadata now resolves through a four-tier waterfall, first
non-empty source wins:

  1. Frontmatter (items[].caption etc.)
  2. Sidecar file next to the image - tries six patterns:
     <name>.yaml / .yml / .json and <basename>.yaml / .yml / .json,
     looked up in both site assets and the page bundle (covers album
     mode and page-resource mode alike).
  3. Embedded IPTC/EXIF via Hugo's .Exif.Tags - caption from
     Caption-Abstract / ImageDescription / XPSubject / Description,
     credit from By-line / Artist / Creator. Wrapped in `try` so
     non-EXIF formats and bad metadata never break the build.
  4. Humanised filename - alt fallback only; captions stay empty
     rather than fabricated from filenames.

Also adds a third source mode - content.page_resources: true -
auto-discovers image resources attached to the current page bundle.
Drop-in for blog posts and project pages where photos live next to
index.md; sidecar lookup works inside the bundle too.

Fixes a leading-slash quirk: Resource.Name returns "/media/..." for
site assets but a bare path for page-bundle resources; the path is
now normalised so sidecar lookups land in either layout.

Test site adds two sidecar YAML files (04-cabin.jpg.yaml and
06-mountain.jpg.yaml) - the masonry album demo now picks up titles,
markdown captions, and links from those sidecars without listing any
items[].
