Add organization-scoped branch protection rules that cascade to all
repos within the org. Repo-level rules take precedence; org rules
serve as the fallback when no repo rule matches a branch.
- New table: org_protected_branch (migration v332)
- OrgProtectedBranch model with full CRUD operations
- API endpoints: GET/POST/PATCH/DELETE /api/v1/orgs/{org}/branch_protections
- Inheritance via GetFirstMatchProtectedBranchRule() fallback
- InheritedFrom field added to BranchProtection API response
- Org rules use team-based whitelists (no per-user IDs at org level)
