Merge upstream/main and address Copilot review feedback

Merge resolved conflicts in web/src/{i18n/{en,zh,types}.ts,lib/api.ts}
by keeping both this branch's `profiles` additions and upstream's new
`models` page additions.

Copilot review feedback:
- Implement POST /api/profiles/{name}/open-terminal endpoint (already
  present); align Windows branch to `cmd.exe /c start "" <cmd>` so it
  matches the new test and spawns a fresh window instead of /k reusing
  the parent console.
- Move backslash escaping out of the macOS AppleScript f-string
  expression (Python <3.12 disallows backslashes inside f-string
  expression parts).
- Patch `_get_wrapper_dir` via monkeypatch in
  test_profiles_create_creates_wrapper_alias_when_safe so the test no
  longer writes to the real `~/.local/bin`.
- Extend test_dashboard_browser_safe_imports to scan `.ts` files in
  addition to `.tsx`.
- Switch upstream's new ModelsPage.tsx away from the `@nous-research/ui`
  root barrel onto per-component subpaths to satisfy the stricter scan.
- Fix NouiTypography `leading-1.4` -> `leading-[1.4]` so Tailwind
  actually emits the line-height for the `sm` variant.
- Guard ProfilesPage.openSoulEditor against out-of-order responses by
  tracking the latest requested profile via a ref.
- Replace ProfilesPage's hand-rolled setup command with a fetch to
  `/api/profiles/{name}/setup-command` so the copied command always
  matches what the backend would actually run (handles wrapper-alias
  collisions and reserved names correctly).
- Wire SOUL.md textarea label `htmlFor` -> textarea `id` so screen
  readers and clicking the label work as expected.
