a11y: Select disabled (UI31), native colorScheme (UI32), touch targets (W16), High Contrast (W18)

UI31 — the native <Select> wrapper now takes a `disabled` prop that passes to
the <select> and applies disabled foreground/background/stroke tokens +
not-allowed cursor, so it can show a disabled state like Fluent controls.

UI32 — dropped the datetime-local's explicit colorScheme:'light dark' so it
inherits the resolved in-app scheme from the app root; the native calendar popup
now follows the app's Light/Dark theme, consistent with the native <Select>,
instead of tracking the OS preference.

W16 — the icon-only row-action clusters (QueueItem + HistoryView) enforce a
>=40x40px hit target via a `& button` min-size rule (glyph unchanged, subtle
button just gains padding). Labels were already non-hover-only: the shared Hint
shows on :focus-within and every action has an aria-label. LibraryView item rows
have no icon-only actions, so nothing there needed changing.

W18 — defended the two color-meaning surfaces against forced-colors: accent
swatches set forced-color-adjust:none (they're color previews; otherwise all
flatten to one system color), and the SegmentedControl active segment paints
with system Highlight/HighlightText under @media (forced-colors: active) so the
checked state stays visible. Status chips (Fluent Badge) and thumbnail tints
correctly let the system palette win.

typecheck + 253 tests + eslint + prettier + production build all green.

*Fixed in [Select.tsx](src/renderer/src/components/Select.tsx): a `disabled` prop passes through to the

swatches, and thumbnail tints use explicit background colors that Windows forced-colors mode may not
adapt (nothing sets `forced-color-adjust`). **Standard:** test under each Contrast theme; let system colors win.
*Fixed the two surfaces that convey meaning through color and would otherwise break under `forced-colors`:
the accent swatches ([settingsStyles.ts](src/renderer/src/components/settings/settingsStyles.ts)) now set
`forced-color-adjust: none` so the accents stay distinguishable (they're color previews — otherwise all
flatten to one system color), and the [SegmentedControl](src/renderer/src/components/ui/SegmentedControl.tsx)
active segment paints with the system `Highlight`/`HighlightText` pair under `@media (forced-colors: active)`
so the checked state stays visible once the brand background is flattened. The status chips are Fluent
`Badge`s (Fluent supplies its own forced-colors handling) and the thumbnail tints are purely decorative
placeholders, so both correctly let the system palette win. Live verification under each Contrast theme is
still worthwhile but the color-meaning surfaces are now defended in code.*
- [ ] **(ref) No semantic headings / radiogroup arrow-nav / focus rings** — UI33, UI30, UI2829 (all bear on Narrator + keyboard users).
