Add @require_scopes("openid") decorator to OAuth backend tools
(provision_nextcloud_access, revoke_nextcloud_access, check_provisioning_status)
to ensure they're only visible to authenticated OIDC users.
Design rationale:
- OAuth provisioning tools are "meta-tools" that manage authentication itself
- They don't access Nextcloud resources, so don't need resource scopes
- Requiring 'openid' ensures user is authenticated via OIDC
- Enables Progressive Consent: users authenticate first, then provision access
- Aligns with dual OAuth flow architecture (Flow 1 + Flow 2)
Changes:
- Add @require_scopes("openid") to all three OAuth provisioning tools
- Update test expectations: users with only OIDC default scopes
see OAuth provisioning tools but not resource tools
- All tests pass (13/13 in test_scope_authorization.py)
