fix(ui): honor model view scope

Two bugs in the models tab, both still present on `main`:

1. `teamIdForQuery` was derived from the team picker alone, so "All Proxy
   Models" still sent `teamId` and the tab showed the current team's models
   under a heading that promises every model the user can reach.

2. `handleViewModeChange` was the only handler that changes the result set
   without passing `page: null`. Switching view while past page 1 kept the old
   page number against a different, usually shorter, list -- so the user saw an
   empty table or skipped earlier rows until they paged back manually.

Rebuilt on `main`: this PR was opened against the since-deleted
`litellm_internal_staging`. `main` has since moved this component onto
`useQueryStates`/`setTableState`, so the pagination fix is now one `page: null`
in the same shape as its siblings (`handleTeamChange`, the search handler, the
access-group handler all already pass it) rather than the `resetToFirstPage()`
call the original patch used. The test is rewritten against `main`'s
`renderWithProviders` + `onUrlUpdate` idiom, and the view label is
"All Proxy Models" here rather than "All Available Models".

NOT VERIFIED LOCALLY: the dashboard's deps will not install in this
environment -- `npm ci` refuses with `Required: {"node":">=24.14.1"}` against
node v22.22.3 -- so `vitest` could not be run on the new case. The source
change is four lines and matches the surrounding idiom; CI's own run is the
real check here, and I will fix whatever it reports.
