Airdrop Claim

[rithvikvibhu]

This PR adds a wizard to claim rewards from the airdrop by providing SSH/PGP keys. It's also possible to skip it and directly input the proof like before.

The file app/background/claim/airdrop.js is taken from the hs-airdrop repo, modified to export functions instead of as a cli script, and also pass along status updates.

A new ducks/claims handles logic for creating the proof, it can probably used for name claims also.

hm, I'm uncomfortable with copying and pasting private keys, that seems super dangerous and clipboard contents may be accessible by other applications, even after the claim process is done. We already have enough issues in hs-airdrop by users who don't want to trust our software with their password. I think opening a file would be at least feel a little more secure.

Bob Wallet is an alternative. Not all users are that concerned with copy/paste keys, or they may have different levels of trust on their device/environment.
The way I see, it's hs-airdrop job to make it as much secure as it could be. Bob's job is to make it more user friendly.

That said, we could have both: paste or select file. We could also clear the clipboard area after use.

Will add a file select then. Will need to consider both armored and binary for pgp, but shouldn't be a problem.

About the clipboard clear, it's not really a bulletproof solution because there are clipboard managers that store a history - in both Windows (built-in) and Linux (kde at least).
Don't want to provide a false sense of sec and let people rely on that. We could add a text reminding them to clear it manually though.

Added file selection, now handles ssh, pgp, asc, gpg files (hs-airdrop already does it well).
