Fix configured model not taking effect for newly created providers

[Copilot]

After configuring a new custom model provider (e.g., minimax), the system continues using the cloud model (e.g., Claude) because setModelType('custom') never executes.

Root cause

In handleVerify, after saving a new provider, the flow is:

1. setForm(...) — async React state update with the new provider_id
2. handleSwitch(idx, true) — reads form[idx].provider_id from the stale closure

For new providers, provider_id is still undefined at step 2, so the /api/provider/prefer call fails validation (provider_id: int), the catch swallows the error, and setModelType('custom') inside the try block is skipped.

Fix

• Add optional providerId parameter to handleSwitch (mirrors existing pattern in handleLocalSwitch)
• In handleVerify, extract provider_id from the freshly fetched provider list and pass it directly:

const savedProvider = providerList.find(
  (p: any) => p.provider_name === item.id
);

if (savedProvider?.id) {
  await handleSwitch(idx, true, savedProvider.id);
}

const handleSwitch = async (
  idx: number,
  checked: boolean,
  providerId?: number  // new optional param
) => {
  // ...
  await proxyFetchPost('/api/provider/prefer', {
    provider_id: providerId ?? form[idx].provider_id,
  });
  setModelType('custom');
  // ...
};
