This commit introduces a refactoring in various page templates to use a central, common 'head' section, stored under utilsHead.html. This head section contains common metadata, styles, and scripts. This change enhances code reusability and standardizes the head section across different pages for consistent user experience and ease of future potential changes. Also, some minimal adjustments were made in the navigation and link routing for more user-friendly URL paths. Lastly, the server's listening interface was updated to only listen on the localhost.
This commit enhances the user experience in two ways:
1. The feedback messages within the setup1.html file have been updated for both the username and password fields. The new messages better inform users about the rules for valid input— stating that the username must be 3-20 characters long and the password must contain at least eight characters.
2. The password validation process has been adjusted. Now, only the confirm password field gets marked as invalid when the entered passwords don't match. This helps users understand exactly which field needs correction.
