Changelog Entry

Description

This PR fixes a case sensitivity issue in the trusted header authentication flow that caused "User mismatch" errors. The problem occurred when identity providers (like Authentik) returned email headers with uppercase characters, while Open WebUI stores emails in lowercase. The new security check in v0.6.14 performed case-sensitive comparison, causing authentication failures after initial login. This fix implements case-insensitive email comparison to match Open WebUI's existing email normalization strategy.

Fixed

Case sensitivity issue in trusted header authentication that caused "User mismatch" errors when identity providers preserve email case

Signup process always stores emails in lowercase
Security check now uses case-insensitive comparison to match this normalization
