Simplify description and option names in the Lock modal dialog

[sarthaknagoshe2002]

Fixes: #62843

What?

This PR simplifies the description and renames the options in the Lock modal dialog to make the interface clearer and more intuitive for users.

Why?

The original description was too long and confusing, with mismatched visuals and terminology that added cognitive load. Additionally, the varying verbs for options were inconsistent and unnecessary. Simplifying the language and standardizing the option names enhances user understanding.

How?

1. The description was updated to focus on user intent: "Choose 'Lock all' to disable all actions, or select specific features to lock."
2. Option names were standardized to:
   • Lock all
   • Lock editing
   • Lock movement
   • Lock removal

Testing Instructions

1. Add a Navigation block to a post.
2. Select the Navigation block and click Options > Lock.
3. Observe the updated description and option names. Ensure the visual order aligns with the description.
4. Verify the interface is now clearer and easier to understand.
