joaomarcos 2a4542333e fix(photon): classify Envoy overflow errors as retryable; add typing cooldown
Closes #50185

Two independent gaps let a transient Photon/Spectrum upstream overflow
degrade message delivery and amplify gRPC pressure:

1. _is_retryable_error did not recognise Photon- or Envoy-specific error
   strings ("internal sidecar error", "upstream connect error",
   "reset reason: overflow"), so _send_with_retry fell through to the
   plain-text fallback immediately instead of backing off and retrying.

2. send_typing had no rate gate, so a burst of typing-indicator calls
   during an overflow event kept hitting the upstream gRPC connection and
   widened the failure window.

Fix:
- Add _PHOTON_RETRYABLE_PATTERNS with the three high-specificity Envoy /
  sidecar substrings and override _is_retryable_error on PhotonAdapter to
  check them after delegating to the base-class patterns.  base.py and all
  other adapters are untouched.
- Add a 5 s per-chat cooldown in send_typing backed by _typing_last_sent.
  stop_typing clears the entry so the next start after a completed turn
  fires immediately — only rapid consecutive starts without a stop are
  suppressed.
- Reduce PhotonAdapter._send_with_retry default max_retries from 2 to 1
  (single 2 s back-off check) — enough to confirm whether the Envoy
  circuit-breaker has opened, without adding unnecessary latency.

All changes are scoped to plugins/platforms/photon/adapter.py.
