Fix case repo sync + auto-create Gitea repos + add sync indicator

- auto-sync-cases.sh: fix broken directory scan (was looking for
  status subdirs that don't exist), fix env var word-splitting bug,
  add safe.directory handling and error logging
- cases.py: auto-create Gitea repo on case_create, fix
  documents/original → documents/originals naming mismatch
- app.py: add GET /api/cases/{case_number}/git-status endpoint
- web-ui: add SyncIndicator component in case header showing
  sync status (synced/pending/no remote) with last commit time
- pyproject.toml: add httpx dependency
- CLAUDE.md: update Paperclip wakeup API docs
- settings page: switch tag input from Select to free-text with datalist
