feat(modpackchecker): Phase 5 complete - Dashboard badge and cron job

Phase 5 Components (completing Pyrrhus's work):

NEW FILES:
- views/dashboard/UpdateBadge.tsx: Dashboard badge component
  - Shows 🟢 (up to date) or 🟠 (update available) next to server names
  - Global cache prevents multiple API calls on page load
  - Reads from local database, never calls external APIs directly
  - Fire (#FF6B35) and Frost (#4ECDC4) brand colors

- console/CheckModpackUpdates.php: Laravel cron command
  - Run with: php artisan modpackchecker:check
  - Loops through servers with MODPACK_PLATFORM variable
  - Checks CurseForge, Modrinth, FTB, Technic APIs
  - Rate limited (2s sleep between checks)
  - Stores results in modpackchecker_servers table

UPDATED FILES:
- Controllers/ModpackAPIController.php:
  - Added getStatus() method for dashboard badge endpoint
  - Returns all user's servers' update status in single query
  - Added DB facade import

- routes/client.php:
  - Added GET /extensions/modpackchecker/status route

- build.sh:
  - Complete rewrite for Phase 5
  - Handles both console widget AND dashboard badge
  - Auto-detects extension directory (dev vs extensions)
  - Copies CheckModpackUpdates.php to app/Console/Commands/
  - Injects UpdateBadge into ServerRow.tsx
  - Clear status output and next-steps guide

Architecture (Gemini-approved):
  CRON (hourly) → Database cache → Single API endpoint → React badge
  Dashboard badge is 'dumb' - only reads from cache, never external APIs

Completing work started by Chronicler #62 (Pyrrhus).
UpdateBadge.tsx was lost in Blueprint corruption - reconstructed from
handoff notes and architecture documentation.
