gsxdsm fe5a595984 FN-7622: unify desktop and CLI provider seeding to fix truncated provider list

The Electron desktop app's in-process dashboard server skipped the CLI's provider seeding sequence, so /api/providers and /api/models returned a truncated catalog (missing built-in API-key providers and user customProviders[]) compared to the identical config on the web build.

- Move provider-auth.ts and custom-provider-registry.ts from @fusion/cli into @fusion/engine as the single shared implementation
- Add engine/src/provider-registration.ts exposing seedDashboardProviders(), mirroring the CLI's exact startup order (built-in Zai provider registration -> wrapAuthStorageWithApiKeyProviders -> model merge/refresh -> registerCustomProviders -> settings:updated resubscription)
- Update desktop/src/local-runtime.ts and local-server.ts to call the shared seedDashboardProviders() helper instead of constructing a raw authStorage/modelRegistry
- Convert packages/cli/src/commands/provider-auth.ts and custom-provider-registry.ts into re-export shims preserving unchanged observable behavior
- Add engine/src/__tests__/provider-registration.test.ts and expand desktop local-runtime/local-server tests to cover the shared seeding path
- Add changeset for @runfusion/fusion (patch)
