fix(backend): Align enterprise connection create and update params with the Backend API

[manovotny]

Description

Stacked on #9153. This finishes aligning CreateEnterpriseConnectionParams and UpdateEnterpriseConnectionParams with the Backend API contract (clerk_go api/bapi/v1/enterprise_connections/service.go).

Two commits, reviewable separately:

Required fields and deprecations

• name and domains are now required on create. BAPI validates both (validate:"required", min=1 on domains), so calls without them already failed at runtime — the types now catch it at compile time.
• syncUserAttributes on create is deprecated. BAPI's CreateParams has no sync_user_attributes field; the JSON decoder drops it silently. It works on update, and the deprecation notice points there.
• provider on update is deprecated. BAPI's UpdateParams has no provider field — the provider can't be changed after creation.

Missing optional params

Adds the optional fields BAPI accepts that the SDK types omitted: allowOrganizationAccountLinking, customAttributes, authenticatable, disableJitProvisioning (create and update), disableAdditionalIdentifications (update only), and saml.loginHint. Every shape was verified against the Go structs, including LoginHintParams (mode is one of email_address, custom_attribute, off; source is required exactly when mode is custom_attribute) and the custom attribute array (name and key required). All camelCase names were confirmed to snake-case to the exact wire keys.

To test: pnpm --filter @clerk/backend test:node EnterpriseConnectionApi.test.ts — new tests assert every added field reaches the request body in snake_case.
