<objective>
Remove copy-from-locale from admin `mltext` and `mlmarkdown` fields. Keep one locale selector per field, synchronized across ML controls, and nested `Record<string,string>` save bodies. Copy currently overwrites the active locale with the other locale's (often empty) string, so the editor appears to go blank.

Purpose: Journal UAT — the operator does not want Copy, and the control is lossy.
Output: SPA components and tests, forms.md sentence, rebuilt `modules/boardwalk/dist`, one code commit.
</objective>

Facts:

- Both ML components have a visible locale `<select data-ml-locale>`, a second unlabeled `<select data-ml-copy-from>` (other locales), and a Copy button that runs `copyLocale()`: `values[active] = values[copyFrom] ?? ''`. On create, the other locale is `""`, so Copy blanks the field the operator is editing.
- `otherLocales` and `copyFrom` exist only for that chrome. Locale broadcast (`broadcastMLLocale` / `ML_LOCALE_CHANGE`) stays.
- `docs/backend/forms.md` "Markdown and multilingual fields" currently says "Copy-from-locale fills the active locale from another code already in the value." Delete that sentence. Historical Phase 14.2.1 PLAN/VERIFICATION files stay as-written.
- Embedded SPA: after Vue edits, `npm --prefix admin run build` then commit `modules/boardwalk/dist`. `scripts/check-admin-dist.sh` is the drift gate.
- Commit rules: one logical change, planning docs not in the code commit, no co-author trailers.

  <action>
In MLTextField.vue and MLMarkdownField.vue, delete copyFrom, otherLocales, copyLocale, the copy-from select, and the Copy button. setLocale only assigns activeLocale. Keep data-ml-locale, broadcastMLLocale, and the editor.

In MLFields.test.ts, rewrite `edits the active locale and copies from another` to switch locale and type into the active field without `[data-ml-copy-from]` / `[data-ml-copy]`. In the existing "one locale selector" case, also assert those copy selectors and buttons are absent on both components.

In docs/backend/forms.md, remove the Copy-from-locale sentence; leave the rest of the paragraph.

Rebuild with `npm --prefix admin run build` and include modules/boardwalk/dist.

Commit: `fix(admin): drop ML copy-from locale chrome` (or equivalent). No .planning files, no trailers.

<success_criteria>
- Clicking around an mltext/mlmarkdown field cannot blank the active locale via Copy, because Copy is not there.
- Switching en/pl still switches every ML control on the form.
- Nested locale maps still round-trip.
