Build and Push Docker Image / build (push) Successful in 24s

ARCHITECTURE.md:
- Directory structure: add middleware/requireAuth.js and favicon assets
- §4.1: remove CORS from middleware list
- §4.2: all proxy routes now auth-required via requireAuth; add
  middleware description
- §6: cookie payload corrected (no token); document secure+sameSite
- §7: add emby:users cache key (60s TTL)
- §8: Download Object table: userTag → allTags/matchedUserTag/tagBadges
- §9 POST /login: document cookie security attributes
- §10: add Tag Badge Rendering section; remove hardcoded line count

Diagrams:
- class-server.puml: add requireAuth middleware module; update
  dashboard.js methods (extractAllTags, extractUserTag w/ username,
  buildTagBadges, getEmbyUsers); add TagBadge value class; add auth
  relationships for all proxy routes
- class-data.puml: Download Object userTag → allTags/matchedUserTag/
  tagBadges; add TagBadge class; remove token from Session Cookie
- seq-auth.puml: cookie payload no longer contains token; add
  secure/sameSite note
- component.puml: remove CORS component; add requireAuth; consolidate
  Emby connection to show tag badge + user-summary usage
- activity-matching.puml: update to extractAllTags/extractUserTag
  (with username); showAll uses hasAnyTag; tagBadges built from
  embyUserMap; add Emby user fetch step; update legend
- seq-dashboard.puml: add emby:users cache lookup / Emby fetch for
  showAll; update matching groups to show tag classification; add
  tag badge rendering note on renderDownloads()

### Tag Badge Rendering
Download cards render tag badges in the card header:
- **Normal user view**: a single accent-coloured badge showing the tag label that matched the current user's username (via `matchedUserTag`).
- **Admin `showAll` view**: all tags on the download are rendered using `tagBadges[]`:
- Tags with **no matching Emby user** → amber badge showing the raw tag label (leftmost)
- Tags **matched to a known Emby user** → accent badge showing the Emby display name (rightmost)
### Auto-Refresh
The dashboard polls the server at the user-selected interval (1s, 5s, 10s, or Off). The status panel auto-refreshes in sync. Client refresh rate is sent to the server on each request for active-client tracking.
