No error message displayed. The phpMyAdmin button simply does not open/respond when clicked.

Other Information

I created a free hosting account (username: if0_42782279) on August 29th and
created a MySQL database (if0_42782279_sistema_pedidos). However, the MySQL
hostname still shows as a generic placeholder (“sqlXXX.infinityfree.com”)
instead of a real server number, and the phpMyAdmin button does not open
anything when clicked. It’s been over 2 days now. Could someone please check
what’s happening with this account? Thank you.

I don’t know where did you get that from, because free hosting MySQL server address really looks like that. And they aren’t reachable from the Internet and does not resolve on public DNS.

phpMyAdmin seems to be working fine from here.

To clarify, do you mean it literally shows sqlXXX or do you mean it shows something like sql210.infinityfree.com?

Because the second is correct (note yours may not be sql210, that is an example as there are many)
