Fix panel member streaming and persist full transcript with images

Three related panel-member improvements:

Tool-box streaming fix: correlate tool boxes by tool ID instead of a
single pointer (fixes orphaned spinners and empty boxes when a member
calls multiple tools in one message), forward CLI ToolEnd to capture the
tool input (command/path), normalize tool names, clean up orphaned
spinners on finalize, and add a blinking cursor during text streaming.

Image/screenshot support: CLI panel members now extract image refs from
the last user message (like the worker) and drop them as temp files
readable via the Read tool, so members can see screenshots and file
attachments instead of being blind on image-based questions.

Reload persistence: each member persists a structured JSON transcript
({name, model, segments:[text|tool]}) instead of plain text, so a reload
restores text AND tool boxes interleaved exactly like live. history.js
renders the transcript and keeps back-compat for the old [Panel: Name]
plaintext format.

- AnthropicService.Agents.cs: NonStreamingLoopCallbacks.TranscriptSink,
  loop collects text/tool segments, tool input added to combined event
- AnthropicService.Panel.cs: CLI member ID-correlation + ToolEnd input +
  image refs + transcript; RunPanelMember persists one JSON transcript
- stream-ui.js: tool boxes keyed by ID, name normalization, cursor,
  orphaned-spinner cleanup
- history.js: render JSON transcript with tool boxes, plaintext fallback
