the plugins screen becomes /marketplace

`/plugins` redirects rather than 404s: the word is in the dock, in the docs and in
whatever anyone bookmarked, and a route that worked yesterday returning nothing
reads as the feature having been removed. The API keeps its name — only the screen
moved — so the permission entry lists both paths, because a client-side redirect
is still a route that has to resolve before it can send anyone anywhere.

Also: the fetch stubs in marketplace.test.ts needed `as unknown as typeof fetch`.
Bun's `typeof fetch` carries `preconnect`, so a bare stub is not assignable —
tests passed while tsgo did not, which is the wrong way round to find out.

tsgo clean, frontend builds, 873 pass / 7 fail unchanged.
