fix(react): keep native select options readable in dark mode

The native <select> option popup follows the control's opaque background
and color-scheme, not option-level styles. bg-transparent left the popup
white, so dark-mode options rendered near-white text on a white surface.
The dark:bg-input/30 fallback never applied: the dark: variant is gated on
a .dark ancestor class this app never sets (theming is prefers-color-scheme
driven).

Give the select a solid themed surface (bg-popover/text-popover-foreground),
add a hover:bg-accent state, and pin color-scheme via useIsDark so the native
popup follows the active theme. Fixes the Resume approvals dropdown in
setup-mcp and mcp-install-card, and every other NativeSelect.

Closes #1227

+Keep native `<select>` dropdown options readable in dark mode. The console themes through `prefers-color-scheme` and never sets a `.dark` class, so Tailwind `dark:` utilities never matched and the native option popup rendered with a light color scheme over dark text. `NativeSelect` now uses a solid themed surface (`bg-popover`) and pins `color-scheme` to the active theme, so the browser draws a matching, readable popup.
