TJ bfcfb71860 fix: show 'Unset' for missing providers in AI models list (#27400)
## Summary

Frontend-only fixes for the `/ai/settings/models` page:

1. **Provider column displays "Unset"** with an info tooltip when a
model's provider has been deleted, instead of "N/A".
2. **Models without a usable provider display as "Disabled"** in the
list, regardless of the stored `enabled` flag. Covers both missing
(soft-deleted) and disabled providers.
3. **Save button re-enabled when only the provider changes** on the edit
page (previously the button stayed disabled because provider changes
lived outside the formik state).

## Scope

Frontend only. The DB constraint
`chat_model_configs_ai_provider_required_when_active` already prevents a
non-deleted model from having a NULL `ai_provider_id`; CODAGT-709
addresses the server-side cascade when a provider is deleted.

## Changes

- `ModelsPageView.tsx`: two `useMemo` maps (`hasProviderByModelId`,
`providerEnabledByModelId`) passed to `ModelRow`.
- `ModelRow.tsx`: `isEffectivelyEnabled = model.enabled && hasProvider
&& providerEnabled`. When `hasProvider` is false, renders "Unset" with a
standard `InfoIcon` tooltip.
- `ModelForm.tsx`: `canSubmit` OR's in `hasProviderChange` so the save
button enables when only the provider dropdown changes.
- `ModelRow.stories.tsx`: four stories covering baseline,
missing-provider (with tooltip assertion), disabled-provider, and
disabled-model paths.
- `ModelsPageView.stories.tsx`: `OrphanedModelShowsUnset` feeds an
orphaned model through the real derivation (map-miss + `?? false`),
matching the production shape produced by `deriveProviderStates`.
`DisabledProviderModelsStillListed` now asserts the "Disabled" badge.
- `ModelForm.stories.tsx`: `EditUpdateEnabledOnProviderChange` asserts
the save button is enabled when the selected provider differs from the
model's stored provider.
- `testFixtures.ts`: `mockOrphanedModel` fixture representing the
deleted-provider case.
