Upgraded Signature-pad.js && Fixed Resizing Canvas on mobile

[Godmartinz]

Description

upgrades Signature-pad.js from 1.5->4.2.0

In order for the signature pad brush strokes to not look pixlated and for the user to be able to sign across the whole canvas on High DPI screens we need the resizeCanvas() method. This fix applies a media constraint to ignore resizing on 767px width and less. effectively not resizing on an ipad mini and smaller.

Fixes #14561 [sc-25246]

PR Summary

• Introduction of "signature_pad" Dependency
  A new dependency called "signature_pad" was introduced into the system. This enhancement is represented in the files package-lock.json and package.json, which keep track of the project's dependencies.

• Improvements to create.blade.php File
  The "create.blade.php" file underwent several changes. The plotting area, generally known as 'canvas', was adjusted to occupy 100% of the available width for a better user interface.

  To enhance the responsiveness of the application, we've added a decision-making routine that resizes the canvas only when the window's width is 768px or higher.

  Additionally, we have removed an event listener that was previously linked to a function named 'resizeCanvas'. This function is not required anymore due to other improvements made to how the application handles changes in size.
