Fix compiler warnings and improve code consistency

- Remove unused imports and comment them for potential future use
- Add missing .send() to HTTP request chain
- Fix integer type suffixes for JSON values
- Simplify async execution by using tokio::block_in_place
- Remove unused function parameters to eliminate warnings
- Extract temporary variables to avoid borrowing issues
- Add placeholder methods to SessionManager for analytics
- Implement real database operations for admin endpoints
- Remove duplicate or conflicting type definitions

These changes address all compiler warnings while maintaining the
existing functionality and preparing the codebase for future
enhancements in areas like analytics and session management.
