MirvMon v0.6.9

v0.6.9 is a behavior-preserving authorization cleanup release.

What changed

Added one RolePolicy for the canonical user, operator, and admin role catalog.
AdminMiddleware, OperatorMiddleware, AdminController, SystemController, and AuditController now consume the same policy instead of duplicating string comparisons.
User-role validation now uses that same catalog, so new role handling cannot drift independently from request authorization.
Existing route permissions are unchanged: users remain read-only, operators keep operational actions, and admin-only credentials/users/system/DR operations remain admin-only.

No database migration or configuration change is required. Pull ghcr.io/mirivlad/mirvmon:0.6.9 and redeploy the existing Compose stack.
