fix(i18n): OpenDyslexic font supports Cyrillic (#513)

* fix(i18n): OpenDyslexic font supports Cyrillic

The OpenDyslexic subtitle in the font picker stated "no RU/ZH support",
but the bundled `@fontsource/opendyslexic` 5.x ships Cyrillic glyphs and
Russian renders correctly — verified empirically. Only Chinese (CJK)
actually falls back to the system font. Updated the subtitle string in
all 8 locales accordingly; the Russian locale itself no longer claims
unsupported-self.

* docs(changelog): correct OpenDyslexic locale-coverage claim (#513)

The #507 entry in the unreleased v1.46.0 block claimed `Latin +
Latin-extended only` and listed Cyrillic among the system-font
fallbacks. Cyrillic glyphs ship in @fontsource/opendyslexic 5.x and
render correctly — only Chinese (CJK) actually falls back. Updated the
bullet in place to match the corrected subtitle hints from this PR.

 * Next step on the accessibility track after the colour-side work (WCAG contrast audits across every theme, dedicated colour-vision-deficiency theme variants for protanopia / deuteranopia / tritanopia): a dyslexia-friendly **OpenDyslexic** font option in the existing font picker.
 * OpenDyslexic uses a heavier weighted baseline and asymmetric glyph shapes — `b`/`d`, `p`/`q` never mirror, italics are differentiated forms rather than slanted regulars — which many dyslexic readers find easier to track than a typical sans.
 * Bundled locally via `@fontsource/opendyslexic` (SIL OFL, freely redistributable). No CDN dependency. The Settings picker grew an optional **subtitle** field on font entries so the OpenDyslexic row carries a "dyslexia-friendly · no RU/ZH support" hint without cluttering the other 14 fonts.
