* refactor(internet-radio): G.86.1 — extract RadioToolbar + AlphabetFilterBar
First cut on InternetRadio.tsx: pulled the two header bars into
their own files under src/components/internetRadio/. RadioToolbar
exports the RadioSortBy type alias so the page state and the
toolbar share the same union. AlphabetFilterBar owns the
A-Z + # key list internally.
Pure code move.
* refactor(internet-radio): G.86.2 — extract RadioCard
Pulled the single radio-station card component (cover, live overlay,
play/delete buttons, name + edit/favourite/homepage chip row) into
its own file. It owns its drag source + the psy-drop listener that
fires onDropOnto with the cursor-side (before/after).
Pure code move.
* refactor(internet-radio): G.86.3 — extract RadioEditModal
Pulled the create/edit-station modal (cover preview + change/remove,
name + stream URL + homepage URL fields, save spinner) into its own
file. station=null means "create new". Pure code move.
* refactor(internet-radio): G.86.4 — extract RadioDirectoryModal
Pulled the radio-browser directory modal (top-stations preload,
debounced search, IntersectionObserver-driven pagination, favicon
+ add-station flow with cover upload from favicon URL) into its
own file. Pure code move.
InternetRadio.tsx is now 299 LOC — every subcomponent lives in
src/components/internetRadio/.
