This commit introduces a range of improvements across the application: - **Security:** - Adds authentication to the CSP metrics endpoint. - Hardens CSP bypass detection regex to prevent ReDoS attacks. - Improves CORS headers for the CSP metrics API. - Adds filtering for acknowledged alerts in security monitoring. - **Performance:** - Optimizes database connection pooling for NeonDB. - Improves session fetching with abort controller. - **Stability:** - Adds error handling to the tRPC demo component. - Fixes type inconsistencies in session data mapping. - **Docs & DX:** - Ignores files in git. - Fixes a token placeholder in the documentation.
