PR Summary

New User Manual Version Added
- A new version (1.1) of the user manual has been added to the system, available in PDF format. It can be found in two locations within the public directories under 'Data/Manuals' and 'files/Manuals'.
Updated User Manual References
- The software has been updated to direct users to the new version of the manual. Specifically, changes have been made in the footers of the admin and web sections of the application. The visible text as well as the file links now correctly reference version 1.1 of the user manual.
Updated Asset Path Handling
- Changes have been made to the way the system handles asset paths for JavaScript and CSS files. The update involves removing any query strings from these paths for better performance and cleaner URLs.
Minor Styling Adjustments
- Some minor changes have been made to the formatting of CSS code associated with input components. These alterations do not affect the functionality of the software, rather they improve the readability and structure of the code.
