refactor(Font): rename fontStore and appliedFontsManager

Both names were vague or overloaded:

- fontStore / FontStore -> fontCatalogStore / FontCatalogStore
  Three font-related stores live in this slice; the new name names the
  paginated catalog specifically.

- appliedFontsManager / AppliedFontsManager -> fontLifecycleManager /
  FontLifecycleManager
  "Applied" collided with the filter-side appliedFilterStore (different
  meaning). The class actually orchestrates a load-use-evict lifecycle
  with FontBufferCache + FontEvictionPolicy + FontLoadQueue
  collaborators, so "Manager" is justified. Companion types file moved
  alongside (appliedFonts.ts -> fontLifecycle.ts).

Directories, file basenames, factory (createFontStore ->
createFontCatalogStore), and the AppliedFontsManagerDeps interface all
renamed. All consumers (ComparisonView, SampleList, FontList,
FontApplicator, FontVirtualList, FilterAndSortFonts bindings,
createFontRowSizeResolver, mocks) updated.
