Open a card from the lockscreen widget without unlock

[hipgnose]

To open the activity over the lockscreen we can't use the setShowWhenLocked(true), we need to define the activity manifest as showWhenLocked=true, as stated in the Android Developers FAQ.

This PR adds the manifest configuration needed to open the activity and disable/hide the activity if the user chose DisableLockscreenWhileViewingCard setting

In the first commit I was finishing the activity if DisableLockscreenWhileViewingCard was off and the lockscreen was up, but I figured out that we can just call showWhenLocked(false) and the activity is sent to behind the lockscreen again.

Notes:

• I tested this in my device and it works without glitches or activities jumping around.
• I didn't use any llm, bot, code agent or something like that, for this or anything in my life.
• Only the test startWithLoyaltyCardNoExpirySetExpiry is failing for me, it says it expected April 22 but receives April 21, I don't know why but maybe it 's something with my timezone?

Fixes #2916

Yeah, known issue. See #2124 and #2460

Do you have any idea how I can test this change btw? Fairphone 6 doesn't seem to have lock screen widgets and neither does the Android 17 emulator in Android Studio.

This is tricky and I still don't have a good answer for you, I'll add here what I found primarily for documentation.

• The Android Developers FAQ says that we can test with Android versions after 16 QPR1 and that it's available in Pixel Tablets link to the FAQ.

• There is also a Pixel Tablet support page showing how to enable lock screen widgets with the "Hub Mode" link to Support

• I tried some emulators with aosp 36.0, with CinnamonBun Preview, even the Pixel Tablet emulator with 36.1 and 37.0 (with gplay) and couldn't find a way to enable the lock screen widgets or the mentioned Hub Mode. The developer options feature flags also don't have a flag to enable it.

So for now I can only test this with my device (GrapheneOS) and don't know how you can reproduce and test.

I can try to run the GrapheneOS in the emulator, do you think it would work for you? I don't know another Android build with the lock screen widgets feature enable /:

I was looking for a way to test but I don't think there is an emulator build available for GrapheneOS, so one step would be to actually build the image and I think it's too much to ask haha
