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.
Changes have been made to support environment specific database file handling. By introducing a new environment variable "DB_FILE", the application's runtime now reads the database file path from the environment. In addition, subdirectories will now be automatically created if they don't exist and more detailed error messages will be printed in case of a failure. Environment variable setup and project building instructions were also updated in the README file.
