Remove CASBIN_DATABASE_URL from line 3.

The code uses individual CASBIN_DB_USER, CASBIN_DB_PASSWORD, CASBIN_DB_HOST, and CASBIN_DB_NAME environment variables (constructed via get_database_url() in crates/service_utils/src/db/utils.rs). CASBIN_DATABASE_URL has no consumers in the codebase and is already labeled as unused; remove it to prevent deployment confusion.

🤖 Prompt for AI Agents 
Verify each finding against the current code and only fix it if needed.

In @.env.example at line 3, Remove the unused CASBIN_DATABASE_URL entry from the
example env file to avoid confusion; update .env.example by deleting the
commented CASBIN_DATABASE_URL line and ensure consumers rely on the individual
vars CASBIN_DB_USER, CASBIN_DB_PASSWORD, CASBIN_DB_HOST, and CASBIN_DB_NAME (as
used by get_database_url() in crates/service_utils/src/db/utils.rs).
