feat: move configurable initial data to genesis

[Arjentix]

🎯 Purpose

After #439 it was clear that state syncing between sequencer and indexer is a bit odd in terms of initial state. Before this PR we shared common initial accounts configuration between them, which was leading to exceptional handling for genesis on indexer side and unclear world state for external viewer.

This PR is the first part of the two. It moves configurable initial accounts data into genesis. In the future PR we will move testnet_initial_state into genesis as well, so that our mainnet and testnet differ only in config files, not in code.

⚙️ Approach

There were a lot of changes, here are the main ones:

1. Indexer no longer have initial accounts configuration at all. It listens for genesis from bedrock as every other block.
2. Wallet no longer have preconfigured accounts. This was dangerous -- private keys stored in config file we don't even plan to encrypt. And this no longer fits into new vision. Instead import command should be used to import external public and private keys.
3. Did some major refactor on wallet side. Replaced account_label with CliAccountMention type to use account ids and labels interchangeably which also reduced a lot of code. Some types were a bit restructured to provide more type-safety and incapsulation. And etc.
4. Sequencer now accepts genesis configuration. Currently the only options there are supply of public and private accounts. This can be expanded in future.
5. Sequencer transforms this configuration into basic transactions by calling genesis_supply_account program. This program is specific to genesis (same as clock program). This program initialize account under authenticated_transfer program and then mints configured amount of native tokens.
6. To bypass some checks (like minting tokens and claiming accounts) is_genesis option was added to validation.
7. Sequencer no longer builds its initial state when existing storage is found, it read the state from storage instead.

lgtm thanks, left some comments

[Arjentix]

Interesting side effect -- valid-proof-test ci job now takes much longer. And 50 minutes are spent on setting up sequencer. That means that genesis transactions are executed pretty slowly on ci hardware.

[Pravdyvy]

lgtm. Mostly agree, Moudy's comments are valid. Left one suggestion about is_genesis flag.
