[Bug]: API Key Management System Incompatibility with Knowhere Backend

[kaiyu96]

Affected area

API keys

Summary

The Dashboard uses Better Auth's apiKey() plugin for API key management, but this plugin's database schema is incompatible with Knowhere API's native API Key system. This causes critical auth failures when users try to use API keys generated in the Dashboard.

Problems:

• Better Auth apiKey plugin creates a different schema than expected by Knowhere API
• API keys created in Dashboard cannot be used to authenticate API requests
• Users see "Unauthorized" errors despite creating valid API keys
• The two systems cannot share or validate the same API keys

Root Cause:

In lib/auth.ts, the Better Auth configuration includes:

plugins: [ jwt(), apiKey(), magicLink() ]

But the generated schema doesn't match Knowhere API's api_keys table structure (SHA-256 hashed keys with user_id, key_mask, etc.).
