Previous fix narrowed `IconProp` to `ComponentType<SvelteComponent<{
size?: number, strokeWidth?: number, class?: string }>>` but Lucide
icons accept `size: string | number` (you can write size="16" or
size={16}), and the resulting structural mismatch surfaces 11 type
errors at every assignment site. Drop the prop-shape constraint
entirely — TrackMenuItem only ever passes numeric values to the icon.
svelte-check on the new dev-push CI surfaced 11 type errors. Cause:
TrackMenuItem typed `icon` as Svelte 5's runes-mode `Component<...>`,
but Lucide-svelte ships class-based components whose type is
`ComponentType<SvelteComponent<...>>`. Switch the prop type to match
Lucide's actual export shape.
Also drop the redundant role="separator" on TrackMenuDivider — <hr>
already implies role=separator (svelte-check warning).
The remaining a11y warnings (tabindex on role=menu/dialog elements,
key-handler-with-click) are pre-existing in FlagPopover and surface
on the new dev-push run because svelte-check now sees them. They're
warnings not errors, so they don't block CI; address as a follow-up.
Single-entry button used by TrackMenu. Supports aria-disabled (kept
visible to preserve menu height when admin-only or pre-#352 entries
are non-functional) and a `danger` flag for the oxblood-tinted
"Remove from library" entry.
