style: cargo fmt

Add startup migration for legacy proxy_config tables that still have
singleton structure (no app_type column) even with user_version=2.

This fixes the issue where v3.9.0-2 databases with v2 schema but legacy
proxy_config structure would fail with "no such column: app_type" error.

- Call migrate_proxy_config_to_per_app in create_tables_on_conn
- Add regression test to verify the fix
