peter c3d88d9b20 refactor: component files export only components; lint fails on a warning
The 43 react-refresh/only-export-components warnings the gate let through meant an edit to a
provider (or AnchoredPopover, Toaster, plexDetailUi, …) could not be hot-swapped: Fast Refresh
reloads a module that also exports hooks or helpers.

- Each provider's contexts, the types its hooks return and the hooks themselves live in a sibling
  context module (navigationContext.ts, channelsContext.ts, …); the provider file keeps the
  component. loadAccountFilters moved next to the feed filters' defaults (feedFiltersInit.ts),
  following navigationInit/playlistsInit.
- Helpers that sat in component files have their own modules: welcomeMode, downloadTitle,
  plexPlayable, channelSync, ui/anchoredPopoverHooks, ui/pageToolbarSlot, ui/pagerContent,
  ui/toastLevels, ui/overlayOrder, ui/tableAlign, lib/plexDetail; the cells of the channel columns
  and the registry's page wrappers are components files of their own (channelCells, modulePages).
- usePersistedTab, an alias of useAccountPersistedState, is gone; its callers use the original.

npm run lint is now eslint --max-warnings 0, so a warning fails the gate like an error does.

// Owns the Playlists module's shared local state — the rail's name filter and the selected playlist
// — lifted out of the App god component so the header search box, the PlaylistsRail, and the
// Playlists detail pane read it via hooks instead of prop-drilling through App. Mirrors
// FeedFiltersProvider / NavigationProvider (split State + Actions contexts, one-line hooks; composed
// in main.tsx around <App/>).
//
// The `search` term is ephemeral (resets on reload, like the other list filters); the selected
// playlist is per-account persisted (LS.playlist) so a reload returns you to it. Neither is
// server-synced, and an account switch does a full reload, so init-from-storage is all the
// hydration these need — no per-account load effect (unlike the server-backed feed filters).
//
// The contexts + hooks live in playlistsContext.ts.
