feat(session): implement Redis storage backend (RC-6) (#4233)

Add RedisStorage as a distributed Storage implementation for the
transport/session package, enabling horizontal scaling of the vMCP
component by externalising session state to a shared Redis/Sentinel
backend.

- Add RedisConfig, SentinelConfig, and RedisTLSConfig structs with
  configurable timeouts (defaults: dial 5s, read 3s, write 3s)
- Implement RedisStorage with Store (SET+EX TTL refresh), Load
  (ErrSessionNotFound on miss), Delete (no-op on missing key),
  DeleteExpired (no-op; Redis TTL handles expiry), and Close
- Support standalone and Sentinel modes; optional TLS with system
  or custom CA roots
- Add unit tests using miniredis covering all methods, TTL refresh,
  idempotent upsert, key format, and all three session types
- Remove nolint:unused annotations from serializeSession/deserializeSession
  now that they are consumed by RedisStorage

Closes #4205
