fix(custom-model,toast): surface the real apply error, and make error toasts sticky with a close button

Two related fixes, both needed to actually diagnose 'Session started on
the native backend — could not apply the custom endpoint' reports from
live testing:

1. runCustomModelEntry()'s apply call went through _apiJson(), which
   unwraps a success body but SWALLOWS a failure response entirely and
   returns null — discarding the one thing (error, errorCode) that would
   tell 'endpoint unreachable' apart from 'not a discovered model',
   'remote/Docker session', or a dozen other real causes the apply route
   already reports distinctly. Switched to _api() so the actual response
   body is read on failure too, and the toast now includes the real
   message.
2. showToast() defaulted every toast, error or not, to a 3s auto-dismiss
   with no way to read it again — exactly what made the above generic
   message impossible to act on even before the fix above. Error toasts
   now default to sticky (duration: 0, no auto-dismiss) unless a caller
   opts into a duration, and every toast — sticky or not — gets an
   explicit close (x) button, since a sticky toast with no way to
   dismiss it would just accumulate across repeated failures.

Tests: custom-model-run-menu-ui.test.ts's two apply tests updated for the
_api() switch (their mocks previously stubbed _apiJson, which the apply
call no longer goes through), plus a new test pinning that the real
server error string reaches the toast on a failure.
