Refactor: remove redundant function name from app.disable

[Ayoub-Mabrouk]

The function name disable was unnecessary since it's already clear from the app.disable property assignment.
Removing it simplifies the code, improves readability, and follows best practices for concise function expressions.

@Ayoub-Mabrouk Thanks, but this is a style change that doesn't bring any improvement.

Additionally for anyone looking at this in the future. Function names are critical for production debugging in many cases. Please name all your functions and preserve names where they already exist. The only exception is for implementation detail functions within other named functions. For example, a callback passed to map is alright not to name if something else in the call stack can be used to help identify it in stack traces, logs, and flamegraphs.
