refactor(translation): split UI from orchestration, dedupe boilerplate

Pure-readability refactor — no behaviour change, all 410 unit tests still pass.

TranslatableRichTextViewer.kt (358 → 192 lines)
- Extract the in-line LaunchedEffect block (cache check + ML Kit await + cancellation
  bridge + result validation + caching) into a private `suspend translateAndCache`
  function. The effect body is now four lines: try/catch around one call.
- Add a small `ResultOrError.toTranslationConfig(content)` extension that returns a
  TranslationConfig only when an actual translation took place, replacing the
  five-condition inline if/else inside the effect.
- Move TranslationMessage / LangSettingsDropdown / CheckmarkRow out to a sibling
  file (TranslationStatusBar.kt). They render the "Translated from X to Y" footer
  and don't belong in the orchestrator file.

TranslationStatusBar.kt (new)
- Renamed the public composable to `TranslationStatusBar` to make its role obvious.
- Split the status text and the dropdown into separate private composables so each
  fits on screen at a glance.
- Add a tiny `LangMenuItem(checked, label, onClick)` to dedupe the four
  `DropdownMenuItem { text = { CheckmarkRow(...) }, onClick = ... }` blocks.
- Hoist `rememberDeviceLocales()` out of the dropdown body for clarity.
- Cache `settings.preferenceBetween(source, target)` once per dropdown render
  instead of calling it twice with identical args.

LanguageTranslatorService.kt
- Extract the in-flight cache plumbing into a `private inline fun dedupe(key, factory)`
  helper. `autoTranslate` is now three lines that read top-to-bottom:
  pre-filter, dedupe, identifyLanguage → translateOrSkip.
- Promote the inline `when` deciding whether to translate (matches translateTo,
  is "und", is in dontTranslateFrom) into a named `translateOrSkip` function so
  the policy is greppable.

TranslationDictionary.kt
- Add a `private inline fun Pattern.forEachMatch(text, block)` extension.
  The four near-identical `val matcher = …; while (matcher.find()) addUnique(matcher.group())`
  loops collapse to three one-liners; the URL detector loop stays explicit because
  it has its own filter.

`inline` on dedupe and forEachMatch keeps the lambda allocations gone, so this is
a zero-cost refactor at runtime.
