- feat(types): add Provider.meta and ProviderMeta (snake_case) with custom_endpoints map

- feat(provider-form): persist custom endpoints on provider create by merging EndpointSpeedTest’s custom URLs into meta.custom_endpoints on submit

- feat(endpoint-speed-test): add onCustomEndpointsChange callback emitting normalized custom URLs; wire it for both Claude/Codex modals

- fix(api): send alias param names (app/appType/app_type and provider_id/providerId) in Tauri invokes to avoid “missing providerId” with older backends

- storage: custom endpoints are stored in ~/.cc-switch/config.json under providers[<id>].meta.custom_endpoints (not in settings.json)

- behavior: edit flow remains immediate writes; create flow now writes once via addProvider, removing the providerId dependency during creation
