fix: M2 — harden the management API after adversarial review
Five confirmed findings from a 46-agent review panel:
- Empty --mgmt-token no longer satisfies the non-loopback token gate
  (critical: 'Bearer ' with an empty token authenticated; parse_serve now
  bails on blank tokens and mgmt::run treats blank as none)
- axum's built-in body rejections (400/415/422) now wear the documented
  ApiError envelope via an ApiJson extractor, and the spec documents them
- GET /health carries security([{}]) in the spec, matching the server's
  auth exemption
- unpairClient's description no longer claims revocation the TLS layer
  doesn't enforce yet (gamestream/tls.rs accepts any cert — known gap)
- CLAUDE.md/README.md no longer reference the deleted web.rs
