Adds org-level tag protection as a parallel to org-level branch protection.
An org tag rule is {NamePattern, AllowlistTeamIDs}; it cascades to every repo
in the org and layers on top of the repo's own protected tags — a tag is
controllable (push/delete) only if allowed at BOTH levels (fail-closed).
- models/git/org_protected_tag.go: OrgProtectedTag model + CRUD +
ToProtectedTag() (reuses the ProtectedTag matcher/allowlist logic) +
IsUserAllowedToControlTagInRepo() which ANDs the repo decision with the org
decision. Migration 363.
- API: /orgs/{org}/tag_protections CRUD (routers/api/v1/org/tag_protection.go,
DTOs in modules/structs/org_tag.go, wired in api.go).
- Enforcement: the git push/delete hook (hook_pre_receive.go) and the two
release paths (release.go create/delete) now call the layered check, so no
per-site tag logic changes beyond swapping the helper.
- View: the repo Tag settings page lists inherited org tag rules read-only.
Stacked on #728 (branch-protection PR) for migration ordering — merge #728
first. Swagger annotations omitted (can't regenerate the swagger JSON without
the toolchain); routes still register.
Note: no Go toolchain available locally, so not compiled/gofmt'd/tested here.
Hand-verified: gofmt (tabs, no blank-in-block, struct alignment), template
nesting balances, all .Rule fields exist on OrgProtectedTag, all locale keys
defined, JSON valid, migration contiguous (363).
