refactor: prevent the user from selecting more than 16 nfts

[patricio0312rev]

[galleries] prevent users from selecting more than 16 NFTs

Summary

• Now the user won't be able to select more than 16 NFTs to a gallery, even if they have been stored or they are being selected (since the limit is 16, we count the alreadyAddedNfts + recentlySelectedNfts to make sure this is <= than the limit).
• NftImageContainer component has been refactored to support this change.
• New unit test for this test case.
• New translations for the tooltip message.

Steps to reproduce

1. Run the app in local or testing_e2e mode.
2. Make sure the wallet you are using for testing has more than 16 NFTs.
3. Go to /galleries page and click on Create a gallery button.
4. Select more than 16 NFTs (you can first add 3, then select other 13, the message considers both added and selected counts).
5. Hover or try to click on the 17th NFT you wanted to add and see the magic ✨
