Add case insensitivity and support for the letter "Ё" in search

Currently, the search functionality in Adalo apps is case-sensitive and does not handle the letter “Ё” in the Russian language properly. This causes inconvenience for users, as they cannot find entries if the text is entered with differences in case or if “E” is used instead of “Ё”.

We kindly request an enhancement to the search function to make it case-insensitive and to account for such specifics of the Russian language as the use of the letter “Ё”. This will make Adalo apps more user-friendly for the Russian-speaking audience.
