forgejo: org-aware mirror sync with credential fix

- Mirror org repos under their actual org (getcompanion-ai/repo) instead
  of flattening to harivansh-afk/org--repo
- Auto-create Forgejo orgs when new GitHub orgs are encountered
- Embed GitHub token in git remote URLs after migration to fix Forgejo's
  broken credential storage for mirror fetches
- Enable Forgejo Actions
