Kyle Isom 871b1fb8f4 Add record-level authorization for system accounts
Record mutations (create, update, delete) no longer require admin role.
Authorization rules:
  - admin: full access (unchanged)
  - system mcp-agent: create/delete any record
  - system account α: create/delete records named α only
  - human users: read-only (unchanged)

Zone mutations remain admin-only. Both REST and gRPC paths enforce the
same rules. Update checks authorization against both old and new names.
