fix: pass user attributes during loginUserWithUserAttributes on Android (#391)

* fix: pass user attributes during loginUserWithUserAttributes on Android

The Android native module was silently dropping all attributes except
email and userId when calling loginUserWithUserAttributes. This chains
Registration.withUserAttributes() using the existing buildUserAttributes
helper, matching the iOS behavior. Also updates the TypeScript type to
accept full UserAttributes instead of only email/userId.

* fix: simplify loginUserWithUserAttributes type to UserAttributes

Address PR review feedback: the union type enforcing email|userId at
compile time is unnecessary since the native layer validates at runtime.
