* feat(gateway): persist webchat inbound images to disk
Images sent via the webchat control UI (chat.send RPC) were parsed into
content blocks but never written to disk, unlike WhatsApp and Telegram
handlers which call saveMediaBuffer(). This caused:
- Images lost after conversation compaction (only existed as ephemeral base64)
- Image editing/generation workflows failing for webchat-origin images
- Incomplete ~/.openclaw/media/inbound/ directory
After parseMessageWithAttachments extracts parsedImages, iterate and
persist each via saveMediaBuffer(buffer, mimeType, 'inbound'). Uses
fire-and-forget (.catch + warn log) so disk I/O never blocks the
chat.send response path.
Fixes#47930
* fix(gateway): address PR review comments on webchat image persistence
- Move saveMediaBuffer calls after sendPolicy/stop/dedupe checks so
rejected or retried requests don't write files to disk (Codex P1)
- Await all saves and collect SavedMedia results into persistedImages
so the persisted paths are available in scope (Greptile P1)
- Preserve Error stack trace in warn log instead of coercing to
toString() (Greptile P2)
- Switch to Promise.all for concurrent writes
* fix(gateway): address remaining review comments on webchat image persistence
- Revert to fire-and-forget pattern (no await) to eliminate race window
where retried requests miss the in-flight guard during image saves
- Remove unused SavedMedia import and persistedImages collection
- Use formatForLog for consistent error logging with stack traces
- Add NOTE comment about path propagation being a follow-up task
