fix: resolve critical runtime errors blocking permission modal

This fixes two severe bugs:
1. Missing debugConsoleStore import causing undefined variable errors
2. Replace non-existent .log() method with console.log()
3. Add #[serde(default)] to HikariConfig to handle missing fields gracefully

The undefined variable was causing initialization to fail, which prevented
the permission modal from displaying properly.
