Fails to login when Kwallet is default keyring
Metadata
Current evaluation
KWallet-backed Snapcraft login fails with “python-dbus not installed”; maintainers agreed to add python3-dbus as a stage package, but the current snap manifest still omits it.
Suggested action: keep open
Reason: The issue has a clear trace and reproducible Ubuntu 24.04/24.10 environment, and a maintainer agreed that python3-dbus should be a stage package. However, snap/snapcraft.yaml still contains no python3-dbus entry and no resolving commit was found, so the valid bug remains open despite inconsistency on other installations.

Issue body
### Bug Description
When Kwallet is default keyring, snapcraft throws an error that `python-dbus` is not installed. I assume, therefore, that `python-dbus` is not included in the snap and therefore it is unable to communicate with dbus in the system.
### To Reproduce
Install snapcraft `snap install snapcraft` on Kubuntu or Ubuntu Studio
Attempt `snapcraft login` or any other item where snapcraft requires access to the system keyring
Most of the time* it will fail with:
```
snapcraft internal error: RuntimeError('python-dbus not installed')
```
*I say most of the time because this is inconsistent between installations, but this happened on a clean install I did to alleviate any error on my part. I have a separate upgraded install where it worked, but this is reproducible 100% of the time on the clean install.
### Environment
Running on Ubuntu Studio 24.10, but this has happened under 24.04 LTS as well.
### snapcraft.yaml
```yaml
No relevant snapcraft.yaml as this happens when merely accessing the keyring via `snapcraft login` or `snapcraft upload` or the like.
```
### Relevant log output

### Additional context
I believe this can be alleviated by simply including `python-dbus` in the snapcraft snap, but this is theory.
