Adds a visual asset library to the social calendar form, backed by
the firefrost-operations-manual branding/ directory with on-the-fly
thumbnail generation via sharp.
- src/routes/admin/branding-assets.js: /list scans both branding/ and
docs/branding/ recursively, groups by category directory. /thumb
generates 256px webp thumbnails from source, caches to disk keyed
by sha1(path + mtime) so edits bust the cache automatically. Path
traversal protection + scope check on thumb requests.
- src/views/admin/social-calendar/_assets.ejs: modal body with
category-grouped grid of lazy-loaded thumbnails, click-to-insert.
- Form modal gets a 'Browse assets' button next to Media Notes.
- Calendar shell gets a second modal (higher z-index) and a
sppInsertAsset() helper that appends the clicked filename to the
media_notes textarea.
Infrastructure (not in repo):
- /opt/firefrost-ops-manual clone added to Command Center
- /etc/systemd/system/firefrost-ops-sync.{service,timer} pulls
every 15 minutes to keep assets fresh
- /var/cache/arbiter/branding-thumbs created for thumb cache
- sharp added as Arbiter dependency (libvips 8.17.3)
