Subject: [PATCH] Remove legacy Internet Identity auth method and add guided
 upgrade flag to id.ai

Internet Identity has migrated to id.ai, and legacy identity.ic0.app is no longer
necessary as it now redirects to id.ai. Following the migration guide from:
https://forum.dfinity.org/t/migrate-your-app-to-id-ai-for-internet-identity-sign-in/63708

- Remove "Internet Identity (Legacy)" authentication method
- Add feature_flag_guided_upgrade=true parameter to id.ai URL for mainnet/staging
