fix(custom-models): Issue #291 regressions and UX improvements

[ditschi]

Summary

Fixes issue #291: custom model manager regressions (unlock model assignment, list/pagination behaviour, loading state, mobile layout, dialog titles/i18n, Toniecard cleanup, legacy JSON handling, Prettier for CI).

Screenshots were taken with Playwright against a local dev instance (German UI), committed under docs/pr-screenshots/issue-291/ on this branch.

UI (Playwright captures)

Custom-Model-Editor — overview

Filter and pagination

Edit custom model

New custom model

Mobile layout

Tonies — Library (list context)

Tonies — Edit modal (Tonie/Tag, model assignment)

---

Test plan

• Custom-Model-Editor: load list, filter, pagination, Zeige alle, edit/save/duplicate/delete.
• Tonies overview: open edit modal; assign model where applicable.
• Library: after save, list page behaviour matches expectation (New custom model manager - collection of improvements #291).
• npm run format:check passes.

Quick context: most of this work was AI-assisted (Cursor/agents). I then rebased onto develop, did manual checks in the dev sandbox, Playwright smoke tests for the #291 points, and a manual code pass. Happy for review where you want extra human scrutiny.

As said. The images in library view are still missing. Also in select a new source (select file file browser). It’s also shown in your screenshots:

All taf information except of the image is shown.

this should be revert to the same behaviour as it was before the first merge with the custom model editor.

and please remove the big folder icon image in case of a folder. That’s ugly and weird. Two times the folder icon. Thank you!

The margins of the in field icons still not correct. Actually it’s worsened. It changed the wrong icons. Dumb ai.

I assume any mobile thing in the editor is also not solved?
