Feature Request: Save Snippet via Keyboard Shortcut (Ctrl + S)

Locate the JavaScript entry point that defines saveSnippet() and controls the snippet modal. Trace how the Save Snippet button invokes the form's native validation, then handle Ctrl + S and Cmd + S only while the modal is open. Done means the shortcut saves valid snippets, preserves validation for empty Title, Category, or Code fields, blocks the browser dialog in the modal, and leaves it unchanged elsewhere.

Description

When adding or editing a snippet in the modal window, users naturally want to press Ctrl + S (or Cmd + S) to save the work. Right now, doing this triggers the browser's default "Save Page As" dialog. We need to intercept this shortcut to save the snippet instead, but only when the modal is open.

Expected Behavior

• When the snippet modal is open, pressing Ctrl + S or Cmd + S should trigger the saveSnippet() function.
• The browser's default "Save HTML Page" prompt must be strictly blocked.
• If the modal is not open, Ctrl + S should be ignored by our script, allowing the standard browser behavior.
• If the required fields (Title, Category, Code) are empty when the shortcut is pressed, the native form validation should still trigger, exactly as it does when clicking the "Save Snippet" button.
