perf(auth): Make aiohttp auth server read-only

Refactored the aiohttp authentication server to be a purely read-only service. Removed all file write operations from the authentication logic to eliminate disk I/O and reduce CPU overhead during connection attempts.

The responsibility for persistently blocking users by writing to `users.json` is now fully delegated to the external scheduler service, allowing the auth server to function as a faster, more efficient gatekeeper.
