fix: scope all git, activity, webhook, and summarize-title routes to correct project store

- Fix 30 git routes to use getScopedStore(req) instead of global store
- Fix activity GET/DELETE routes to use scoped store
- Fix POST /api/github/webhooks to use scoped store for badge updates
- Fix POST /api/ai/summarize-title to use scoped store for settings
- Fix GET /api/git/worktrees to use scoped store for task listing
- Add projectId parameter to all git and activity frontend API functions
- Update useActivityLog hook to pass projectId through
