fix(state-hub): fix mcp-http startup crash and remove legacy tunnel targets

- Add `Optional` to typing imports in mcp_server/server.py — it was used
  in 13 annotations but never imported, crashing FastMCP v3 at startup
- Remove legacy tunnel/tunnel-daemon/tunnel-loop/tunnel-status/tunnel-stop
  targets from Makefile; ops-bridge (tunnels-up/status/check) supersedes them
