Module middleware 

Tower middleware layer that loads, validates, and persists sessions for every request.

The public entry point is layer, which wraps a SessionStore in a Tower Layer / Service pair. The middleware:

1. Reads the session token from the request cookie.
2. Loads the matching, non-expired session from the database.
3. Optionally validates a server-side request fingerprint.
4. Injects shared state so the crate::SessionManager extractor can operate within the handler.
5. After the handler returns, applies any pending session action (set cookie, remove cookie, or touch expiry).
