Add Feed Generators UI and backend algorithm
Server: add algorithm to return paginated scrobbles feed. Client: add
API endpoint, react-query hook, and FeedGenerators component (category
scroller with chevrons). Add constants and index export. Add
@tabler/icons-react dependency and small UI/style tweaks (padding,
z-index, font settings).
