Phase 1 housekeeping for the full-isolation round:
- Move DatabaseSnapshot + SyncJob out of models/wordpress_site.py into a neutral
models/db_snapshot.py (pure module move, tables unchanged); wordpress_site.py
re-exports both for import compatibility.
- Untrack the stale committed live copies of serverkit-gui (sibling repo, no
in-tree source) and serverkit-email (source of truth: builtin-extensions/
serverkit-email/), matching how every other extracted builtin is already
gitignored. Files stay on disk; only removed from the index.
- .gitignore: add the email + gui frontend/backend artifact paths.
