Moved the inline padding style from FlatList into the StyleSheet by creating a listContainer style.

Applied the new style using contentContainerStyle to replace the inline style.Style

I only refactored the inline style in FlatList by moving it into the StyleSheet as listContainer and applied it using contentContainerStyle. There are no other functional or UI changes.

However, I noticed that the Hours section and the UI component have been updated to use TouchableOpacity. Could you please confirm if those changes was part of another task? Just want to make sure we’re aligned on the scope of this PR.
