feat: add GIF Mood Board workshop

- New workshop where each team member shares up to 5 GIFs with notes to express their weekly mood
- Per-user week rating (1-5 stars) visible next to each member's section
- Masonry-style grid with adjustable column count (3/4/5) toggle
- Handwriting font (Caveat) for GIF notes
- Full real-time collaboration via SSE
- Clean migration (add_gif_mood_workshop) safe for production deploy
- DB backup via cp before each migration in docker-entrypoint
