refactor: enhance platform configuration, database schema handling, and Keycloak setup

Improved `PlatformConfig` API base URL resolution with enhanced logging and fallback logic. Revised database initialization with version checks, schema migration, and error handling. Updated Keycloak configuration to enable `Direct Access Grants` and refine CORS/redirect settings. Adjusted Webpack proxy settings for correct API routing.
