video_editor: auto-load mapped config + --map accepts files

Mirror the township config fix for the bundled video editor:
* supervisord: pass --config /cache/video_editor/video_editor.config.json so a
  bind-mounted (or cache-persisted) config auto-loads — previously it only
  auto-loaded video_editor.config.json from the baked cwd, which isn't mappable.
* video_editor.py: a MISSING --config file is no longer fatal (was raise
  SystemExit) — start with defaults; the web UI Save creates it.
* entrypoint: pre-create /cache/video_editor so the config dir exists for
  auto-load + web-UI Save (persists on the standard /cache volume by default).
* run_oci.sh (coderai-docker): --map now accepts a single FILE, not just a dir,
  so a tool config that lives loose on the host can be linked directly, e.g.
  --map /host/video_editor.config.json:/cache/video_editor/video_editor.config.json

Bump version to 0.1.5.
