added country flags

• the only one I haven't tested is the details banner with a lock; I realized I don't actually know what the password is to the test data lol
• I followed the one in figma for the micro crowdaction cards where the country flag is to the left of the lock icon. I wanted to double check on this though because in everywhere else, the lock icon comes first.

The alignment of the flag vs. the lock icon is correct, it's because of it being RTL on the CrowdAction Card and Banner, whereas on the Micro Card it's LTR.

@eStarKee06 Can you resolve the analyzer error so we can merge? :+1:

There are crowdactions without a password, and the password is most likely veganuary-2022
