Merge Core main into german/hal-644-ar: Arabic on the Vue UI

Main moved the UI to Vue views and Pinia stores, so the Arabic changes to
the old DOM controllers now live in their views: the rail legend range
comes from formatScaleRange (keeping units a source supplies as given),
the voice timeout options are worded by Intl unit formatting in
VoiceControl, and the scene editor's JSON fields stay left to right in
SceneDialog. Main's CCTV status line, launch panel and calibration values
keep the Arabic isolates and Western-digit formatting.

isolate() and keepCodesWithValues() read the locale through getLocale(),
which follows the page's vue-i18n instance, and the Intl formatters take
intlLocale(getLocale()). A language switch now applies in place, and
applyDocumentLanguage sets <html dir> on every switch, so the page mirrors
without a reload.

The icon rails and their tips are placed with logical properties, so they
stay on the outer side of the mirrored stacks; Cyber's new stack offsets,
padding and edge lines are logical too, and rtl.css moves Cyber's right
stack to its new rail clearance. Main removed the Context mini radio, so its
right-to-left rules and test go.

The Arabic catalog gains main's new strings and drops the ones main no
longer uses; the other catalogs keep main's new keys and the branch's
landing labels.

 ## Digits and direction
 
 - **Western digits (0–9)**, as in the catalog. The HUD reads like an instrument panel, and mixing ٠–٩ with Latin codes and coordinates misreads. `intlLocale('ar')` in `src/i18n/locale.js` passes `ar-u-nu-latn` to every Intl formatter, so browsers that default to Arabic-Indic digits for an Arabic region still show 0–9.
-- **Right to left.** `ar` is in `RTL_LOCALES`, so the page gets `<html dir="rtl">`. The title, style indicator and both rails swap sides; the dock and the corner row reverse. The intel HUD (classification block, MGRS, coordinates, GSD) stays a left-to-right instrument overlay; its translated lines read right to left inside it. Media transport (previous / play / next) and the radio dial stay left to right, as on any player. Layout rules: `src/ui/styles/rtl.css`.
+- **Right to left.** `ar` is in `RTL_LOCALES`, so the page gets `<html dir="rtl">`. The title, style indicator, both panel stacks and their icon rails swap sides; the dock and the corner row reverse. The intel HUD (classification block, MGRS, coordinates, GSD) stays a left-to-right instrument overlay; its translated lines read right to left inside it. FM seek and the radio dial stay left to right, as on any receiver. The rails' screen-reader names follow the mirrored layout: «Left panels» is «اللوحات اليمنى». Layout rules: `src/ui/styles/rtl.css`.
 - Latin runs inside Arabic sentences (product names, codes, `{placeholders}` filled with English data) are isolated by the bidi algorithm; write them as plain text, without manual direction marks.
 - Position counters: a translated counter says «من» («القناة {index} من {total}», «الإطار {index} من {total}»); a spaced slash between two isolated numbers swaps them in right-to-left text. Counters the code builds from bare numbers (`01 / 25`, `1 / 3`) are shown left to right by `rtl.css`.
 - Code stays left to right: the JSON fields of the scene editor are LTR in every language.
