feat: Improve dashboard functionality and stability

This commit introduces several improvements to the dashboard:

- Refactored the component structure for consistency, defining callbacks within the `render` function.
- Added robust error handling to data loading and callbacks to prevent crashes.
- Implemented linking for SO and AIR columns in the source table.
- Added and improved filtering and display options for tables.
- Left-aligned columns in tables for better readability.
- Cleaned up unused component files.
