feat(contract): add javascript validation

[Chuck-D-Norris]

This pull request includes several changes to the admin contract and tree type views, as well as improvements to form validation and database schema updates. The most important changes include updating URLs, adding form validation, and modifying the database schema.

URL Updates:

• Updated URLs in app/src/app/Views/Admin/Contract/Create.php, Edit.php, and Contracts.php to include the /admin prefix for better organization and consistency. [1] [2] [3]

Form Validation Enhancements:

• Enhanced form validation in app/src/public/assets/js/app.js by adding reusable validation functions and event listeners for contract and tree type forms. This includes checks for empty fields, regex pattern validation, date range validation, positive integer validation, and maximum value validation.

Database Schema Modifications:

• Modified the contracts table in database/start-scripts/0-init.sql to change the data type of start_date and end_date from timestamp to date for better accuracy and consistency.

UI and Form Adjustments:

• Added error message divs and adjusted form IDs in app/src/app/Views/Admin/Contract/Create.php and Edit.php to improve user experience and error handling. [1] [2]
• Updated form IDs and removed unnecessary divs for submit buttons in app/src/app/Views/Admin/TreeType/Create.php and Edit.php to streamline the UI. [1] [2]
