Rebake team logos at 72×72 for crisp notification thumbnails

The notification thumbnail's native display size is ~48 physical pixels
(measured empirically with a size-ladder test attached via the dev menu).
Shipping logos at 512×342 forced macOS to downsample ~10×, which is what
was producing the blurry/aliased team logos in banner thumbnails.

- Pre-render logos at 72×72 (1.5× over native; stays sharp, gives a little
  extra detail for retina displays without triggering aliasing)
- Trim transparent margins before fitting: NHL brand SVGs pad their
  viewBox generously, so the actual logo was only ~60% of the bundled
  image. square_logo.swift now scans the alpha channel, crops to the
  tight bounding box, then fits aspect-preserved into the 72×72 canvas.
- Drop the 32 unused TeamLogo_*.imageset asset-catalog entries (dead code
  since the team-filter feature was removed); notifications load PNGs
  from the filesystem bundle subdir
- Move TeamLogos/ → Resources/TeamLogos/ and update project.yml source
  paths; excludes: on the recursive scan prevents duplicate flat copies
  that were bloating the bundle
- Simplify NotificationManager: drop SVG fallback (macOS doesn't accept
  SVG attachments) and content-hash identifier experiments; back to the
  minimal working config
- Dev menu: add "Thumbnail Size Test" which fires a ladder of 10 test
  notifications (16…128px) for future sizing verification
- Fire a test game-start notification on startup in DEBUG builds so the
  dev loop doesn't require clicking through the menu after each launch
- Scripts/square_logo.swift: alpha-bbox trim + aspect-preserved fit
