`-- Select --` displayed as Autofill on page load? setting for login items

### Steps To Reproduce

1. Go to Settings and enable _Auto-fill on page load_, and _Auto-fill on page load_ as the `Default autofill setting for login items`
2. Click on a login item in one's vault and edit the login
3. Scroll down to the `Autofill on page load?` setting

### Expected Result

_Default (yes)_ displayed

### Actual Result

_-- Select --_ displayed.

### Screenshots or Videos

### Additional Context

Displaying _-- Select --_ suggests that no option has been selected, and that auto-fill won't work. But, auto-fill does work. So, displaying _-- Select --_ is misleading.
I don't know why it's even possible for the `Autofill on page load?` setting to be _-- Select --_. Surely, it should be _Default (yes|no)_, unless a different selection has been made by the user?

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Reproduce the issue in the login item edit view by enabling both autofill settings, then inspect the client code responsible for the “Autofill on page load?” control and its default-value handling. Confirm the fix by checking that the control displays “Default (yes)” on page load while still reflecting explicit user selections.
