When resend() is called with an email in the PKCE flow, the request now includes code_challenge and code_challenge_method so the resent confirmation link can be completed. Phone and non-PKCE flows are unchanged.

What
When
resend()is called with anemailwhile the client uses the PKCE flow (the default), thePOST /resendrequest now includescode_challengeandcode_challenge_method. Without the code challenge, the resent confirmation link cannot be completed viaexchangeCodeForSession.This brings the Dart SDK to parity with the supabase-js behavior.
Behavior
resend(email:)in PKCE flow includescode_challenge+code_challenge_method: s256in the body.Tests
Added tests covering all three cases above in
otp_mock_test.dart, and captured the resend body in the OTP mock client for assertions.Closes SDK-1023
