fix(typescript): resolve linter violations and improve type safety 

- Remove unused isDev variable
- Add proper type annotations for event handlers
- Add explicit Promise<void> return type for loadIndexHtml
- Use unknown type for error parameters instead of any
- Fix event handler parameters by prefixing unused params with underscore
- Improve error handling type safety throughout the file

This commit improves type safety and removes unused code while maintaining
existing functionality. All TypeScript linter violations have been addressed
without changing the core behavior of the application.

Database paths are still broken here.

Security Impact: None - changes are type-level only
Testing: No functional changes, existing tests should pass
