Handle custom redirectURL overrides in redirect URI matching logic

[coderabbitai]

Context

This issue tracks an enhancement to handle custom redirectURL overrides in the redirect URI matching logic introduced in PR #223.

Problem

The login and register methods allow callers to pass a custom options.redirectURL parameter. However, the new redirect URI matching logic in KindeProvider.tsx only checks against the module-level redirectUri prop. This means callbacks to a per-call redirect URL would skip code handling.

Proposed Solution

Persist the effective redirect URL used for each auth request (e.g., in session/local storage or encoded in the state parameter) and match against that value (or an allowed list) during the redirect handling phase.
