refactor(rbac): migrate API permission checks to resource:action format

Replace all legacy dotted permission codes (vms.view, proxmox.manage, ...)
in PermissionChecker/has_permission across app/api with the new
resource:action format (vm:view, server:manage, ...), per LEGACY_PERMISSION_MAP.
All 33 codes used by the API are now registered in the permission registry.

Also switch the /api/auth/me admin branch to get_all_permissions_v2 so the
endpoint emits permissions in the new format only.
