Cache supply adjustment transactions in explorer codebase

[ericlwilliams]

Problem

Currently, explorer transaction data persists for ~30 days. We would like to persist transactions related to the recent supply adjustment.

Proposed Solution

Cache the following six transactions in explorer codebase for persistent retrieval.

@ericlwilliams @mvines these transactions aren't available anymore from the API. Do you have the info handy?

[ericlwilliams]

@jstarry I'll share a doc with you on slack.

[mvines]

That's surprising because:

$ curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1, "method":"minimumLedgerSlot"}' http://api.mainnet-beta.solana.com
{"jsonrpc":"2.0","result":7665164,"id":1}

and those transactions aren't that old

[mvines]

For example:

The missing transaction history were a side-effect of the mainnet-beta restart and the lack of solana-labs/solana#10358 on v1.1.

We do in fact have these transactions in the RPC node ledger still

@mvines I tried using the ledger-tool to print slot 10440804 and I get a blockstore error:

Failed to load entries for slot 10440804: blockstore error

Did anything change since you queried earlier?

Nvm, I see the conversation in #sdk now!
