Diego Rodrigues de Sa e Souza 58f0ff1b41 cherry-pick(pr-9675): fix(providers): per-provider opt-out for anonymous no-auth fallback (opencode-go/zen 401s) (#9873)
* fix(providers): add per-provider opt-out for anonymous no-auth fallback

API-key providers with anonymousFallback: true (opencode-go, opencode-zen,
pollinations, kilocode) receive a synthetic "noauth" connection whenever all
real connections are terminal (credits_exhausted/banned/expired) or
unavailable. The opencode upstream now rejects anonymous requests with
401 Missing API key, so the fallback adds a guaranteed-failing round trip
and health/reconnect noise before the combo moves on.

Add a noAuthFallbackDisabledProviders settings array (zod-validated,
persisted via /api/settings, following the blockedProviders pattern).
When a provider is listed, maybeSyntheticNoAuthFallback returns null for
anonymousFallback-only providers, so exhausted providers are skipped
immediately as allExpired/allRateLimited while real keyed connections keep
working and recover automatically once quota state clears. True no-auth
providers are unaffected; blockedProviders remains their disable mechanism.
Default (absent/empty list) preserves current behavior.

Provider detail pages for anonymousFallback providers gain an
"Anonymous fallback" toggle (default ON) backed by the new setting.
