Two bugs in one screenshot:
1. LLM called edit_image(prompt=..., ...) but the signature was
edit_image(edit_instruction=..., ...) — mismatch, missing-arg
crash. Renamed the first param to `prompt` so both tools have a
matching, predictable name. System prompt updated with an explicit
'do not invent edit_instruction' line for stubborn models.
2. After fix#1, edit_image still couldn't find the prior generated
image because Open WebUI assistant-message file attachments only
carry {type, url} (no id, no path). _read_file_dict now also
greps the file id out of /api/v1/files/<uuid>/content URLs and
feeds it to Files.get_file_by_id. Verified pattern matches
absolute URLs (https://llm-1.srvno.de/api/v1/files/.../content).
System prompt also now says 'including images you previously
generated in this chat' to nudge the LLM to pick up assistant
outputs as edit candidates.
