Bug: App allows adding a meal with only numbers and special characters in the name

[LeticiaMonteiroo]

Bug description: The app permits users to add a meal where the food name consists only of numbers and special characters, without any letters. This can lead to meaningless or confusing entries.

Expected behavior: The app should require the food name to contain at least one alphabetical character (a-z or A-Z) to ensure meaningful input.

Environment: Android

Possible solution: Add validation to ensure the food name includes at least one letter, rejecting inputs with only numbers and special characters.
