Settings page hosts the language switcher; profile-edit modal removed ...

The interface-language GnSelect now lives on the Settings page (Auto /
English / Українська / Русский) and applies on change, so the Edit-profile
modal — and the pencil button that opened it — are gone. The dead profile
slugs leave the dictionaries.

UX fixes: pagination ellipsis, mobile layouts, tokens table, danger-zone radius ...

- Pagination re-collapses long page runs to "1 2 3 … 22" (AppPagination, same
  look as the kit's) for secrets, audit and admin users.
- Settings metrics: grid columns; metric cards stretch to the full track and
  stack one per row on mobile.
- Danger zone gets the standard 6px border radius.
- Revealed fields: one column on mobile, long values wrap instead of pushing
  the page into horizontal scroll.
- Secrets table on mobile becomes a card list: category stacks under the
  title, purpose column drops out, thead hidden.
- API tokens list is now a full-width table (Name / Scopes / actions).

Polish custom views on kit 1.0: timeline, audit chain, modals ...

- Audit: the GnEmptyState's v-else bound to the GnPagination's v-if, so the
  phantom "No audit events" block rendered alongside a populated table; move
  pagination outside the loading/rows/empty chain and gate it explicitly.
- Timeline: spell out the text fallback inside the per-item slot (a truthy
  dynamic slot always overrides GnTimeline's item.text), humanize created_at
  to local "YYYY-MM-DD HH:mm" in history and audit, pluralize the field
  count, and draw a connector rail between markers.
- Modals/toasts: drop the app-side a-show/a-hide keyframes — kit 1.0 owns
  both transitions itself; align create-modal spacing to the kit's 15px
  rhythm and add a hairline separator between modal sections.

Verified with Playwright screenshots (history, audit, create modal
open/close/reopen) on the live server; no page errors.

Update gnexus-ui-kit to 1.0.0, drop vendored GnModal, use kit tokens ...

Upgrade the git dependency to 1.0.0 (allow-git for npm 12, recorded in
frontend/.npmrc). The vendored GnModal.vue copy is no longer needed: the
kit's overlay transitions are fixed upstream via useOverlayTransition,
and the official component is API-identical. Replace the five hardcoded
palette hexes in styles.css with kit design tokens so theme swaps stay
one import away.

Also restate the form-group hint styles for .tag-input: GnTagInput
renders its hint outside .form-group, so the scoped .form-group
.input-info styles from kit 1.0 miss it and the hint was glued to the
field with no top margin.

Add in-app extension download page ...

Distribute the gnexus-creds browser extension from the service itself.
Package Chrome and Firefox builds into extensions/dist/ with a manifest
describing version, checksums, and sizes; serve them via authenticated
FastAPI endpoints and surface a new Extension tab in the Vue UI with
download cards, SHA-256, and install instructions.
