fix(ui): cmdk wheel-scroll on macOS + match dropdown widths to trigger

Radix Popover swallowed wheel events on cmdk-backed comboboxes for
macOS users — the country / timezone dropdowns were unscrollable with
a Magic Mouse / trackpad. Add an `onWheel` translator on `CommandList`
plus `overscroll-contain` so the list captures the delta directly.
Lights up every cmdk popover (Companies, Residential Clients, Clients,
Yachts, settings).

Country and Timezone comboboxes now constrain popover content to
`w-[var(--radix-popper-anchor-width)]` with sensible `min-w-*` floors
so wide triggers get correspondingly wide popovers.
