Display URL and AndroidApp Autofill Fields in a Separate Section

### Checks

- [x] I have read the Wiki, searched the open issues, and still think this is a new feature.

### Explain the problem clearly and succinctly:

Currently, URL and AndroidApp autofill fields are displayed alongside other custom fields in the KeePassDX entry editor. This makes it difficult for users to quickly identify and manage autofill-related fields, especially when there are many custom fields.

### Describe the solution you'd like:

1. Create a dedicated section in the entry editor for autofill-related fields
2. Move all URL and AndroidApp fields to this dedicated section
3. Ensure proper handling of multiple autofill fields (e.g., URL, URL1, URL2, AndroidApp, AndroidApp1, etc.)
4. Maintain consistent UI/UX with the rest of the application

### Describe alternatives you've considered:

### Additional context:

_No response_

Start by locating the Android entry editor and the code that identifies and renders URL and AndroidApp autofill fields. Trace how numbered variants such as URL1 and AndroidApp1 are handled, then compare the existing editor sections for consistent UI behavior. Done means all matching autofill fields appear together in a dedicated section without losing support for multiple fields.
