[BUG] Save credentials from autofill does not work

### Checks - [x] I have read the FAQ section, searched the open issues, and still think this is a new bug. ### Describe the bug you encountered: The flow for creating credentials from the autofill service does not seem to work. I enter in credentials <img width="1968" height="2184" alt="Image" src="https://github.com/user-attachments/assets/d645d2e4-86d6-4fb7-b1f7-acffa17f8f80" /> The browser offers to save the credentials using Keepass2Android <img width="1968" height="2184" alt="Image" src="https://github.com/user-attachments/assets/54d4ebf8-d434-453e-a991-22f8de6d86b9" /> On this screen, it looks like it's just opened the DB. Nothing to indicate it as saved it or to pick the folder <img width="1968" height="2184" alt="Image" src="https://github.com/user-attachments/assets/afe54cee-82d0-4192-9046-e79e441a62a8" /> I tried Add entry, thinking it would have populated the URL, username and password <img width="1968" height="2184" alt="Image" src="https://github.com/user-attachments/assets/2356c5f2-2cf7-489e-89ca-7cb1e09cb078" /> I also did a quick search to see if it created it in a default directory, but nothing. <img width="1968" height="2184" alt="Image" src="https://github.com/user-attachments/assets/81d3325a-7194-459a-9b92-180c506b06cd" /> I did read https://github.com/PhilippC/keepass2android/wiki/Documentation#creating-a-new-account, and it implies this flow was never implemented, but I'm not sure why. It is a much simpler flow than the one in the FAQ. Phone: Z Fold 7 Browser: Comet (Chromium) ### Describe what you expected to happen: After the "Save username" dialog, it should go into the flow to save the credentials. You should pick the folder and then save the credentials to that folder. ### What version of Keepass2Android are you using? 1.14-r4 ### Which version of Android are you on? 16
