Add UpdateEnabled methods on CredentialRepository, ConnectionRepository, and ScheduleRepository that toggle the is_enabled flag while preserving updated_utc. Expose corresponding Enable/Disable handlers and wire POST /{id}/enable and POST /{id}/disable routes under /api/v1/credentials, /api/v1/ad-connections, and /api/v1/schedules. Each toggle emits an audit event. Also finalizes CredentialService.Test and TestCredentialInput so the existing /credentials/{id}/test handler compiles and runs against an LDAP host using the stored username and decrypted secret.
