Replace legacy isDeveloper/isAdmin/hasRoles checks with
hasPermission/requirePermission across all collections. Add roleDocs
relationship to Users, enlistmentDate to Profiles, and field-level
intel_excerpt permission gate on Profiles. Auto-generated payload-types
updated to reflect the new Roles collection and roleDocs field.
Add the helpdesk Tickets collection with status/priority/category enums, reporter/assignee relationships, activity timeline, and closedAt lifecycle. Register in payload.config and refresh generated types.
