token-2022: Show all extensions

[joncinque]

Problem

Although the explorer has some support of token-2022, it doesn't show any mint or account extensions, which leads to a lot of confusion for people who create mints.

Solution

Everything is provided with JSON-parsed encoding, so:

• create types for all of the JSON-parsed returns
• show each extension

For the most part, each commit corresponds to an extension, except otherwise noted. I wasn't sure about the best way to display all of these, especially those with many fields, so I went with a little header line before showing each field. Let me know what you think of that.

Here are some screenshots of a mint with every extension (minus token group, group member, group pointer, and member pointer):

And an account with all extensions:

And in case you care, here's how you can create your own mega-token:

set -ex
solana-keygen -o mint.json --no-passphrase
mint=$(solana-keygen pubkey mint.json)
solana-keygen -o source.json --no-passphrase
source_pubkey=$(solana-keygen pubkey source.json)
spl-token -ul \
  create-token \
  --enable-close \
  --enable-freeze \
  --enable-metadata \
  --enable-non-transferable \
  --enable-permanent-delegate \
  --enable-confidential-transfers auto \
  --default-account-state initialized \
  --interest-rate 5 \
  --transfer-fee 10 11 \
  --transfer-hook $mint \
  --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb \
  mint.json
spl-token -ul initialize-metadata $mint MegaToken MT https://spl.solana.com/token-2022
spl-token -ul update-metadata $mint Mega Token

spl-token -ul create-account --immutable $mint source.json
spl-token -ul enable-required-transfer-memos "$source_pubkey"
spl-token -ul enable-cpi-guard "$source_pubkey"
spl-token -ul configure-confidential-transfer-account --address "$source_pubkey"

Looks good!

I think longer term we might want to change how these are displayed because I think this is pushing the limits of the table really. Maybe an extensions tab or something?

I don't think any of my comments are blockers, they're mostly just nitpicks about how we're displaying certain values

I would flag the 'Additional Metadata' though because I think there's a real risk there of malicious tokens abusing it. Maybe the easiest fix for now is to make metadata the last extension displayed, and add a header above Additional Metadata?
