Adds French as a UI language, with French catalogs for message keys and source text,
and the French space before a colon in settings labels.
UI languages are now registered in one place, `LOCALES` in `src/platform/i18n.ts` (name
in its own language and `<html lang>` tag); the Language and Region options, settings
validation and `<html lang>` all come from it. The catalog tests read every catalog in
`locales/` and `locales/text/`, so a new file is always checked, and literal message keys
given to `t` must exist in `en.json`. Only Chinese must cover every UI string; French and
Korean show English for text they lack.
Also makes two date tests independent of DST changes.

Adds Korean as a UI language: Settings › Appearance & Behavior › System Settings ›
Language and Region lists 한국어, with Korean catalogs for message keys and source text.
Only Chinese must translate every UI text. Other locales may lack entries and show
the English text for them; their catalogs are still checked for stale entries, keys
English lacks and placeholders that differ from the English text.

Reverts #1122, merged by mistake (wrong PR number) before review and under another change's commit message. Adding UI locales is still an open decision (#914), and the Korean catalog fails the catalog tests on current main.
`openidea --line 120 --column 8 <file>` opens the file at that position (1-based; without --column the line start; clamped). The position is kept by file until the window that opens it takes its launch: new instance, second instance, a project open elsewhere, an already open file. The path argument skips these flags' values.
Closes#829
