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?
