chore: v2.8.73 — Artifacts folder bar restyled; hidden live profile gets a stand-in

- Artifacts: folders are rounded chips with a count badge; rename/delete are
  icons beside the picked folder (double-click renames); New folder is a
  dashed chip; the empty-folder hint mentions drag and drop.
- GET /api/pricing/quota: every Claude row carries its accountUuid.
- Settings → Profiles and the status bar's Usage panel: a profile hidden in
  this browser is left out of the Usage panel too; when the live login is
  hidden, the first visible profile is shown in its place (Logged in now,
  "in use", the % used chip with that profile's own usage). Display only.
