Introduce the ATA program, which derives deterministic per-token holding
accounts from (owner, token_definition) via SHA256, eliminating the need
to manually create and track holding account IDs.
Program (programs/associated_token_account/):
- Create, Transfer, and Burn instructions with PDA-based authorization
- Deterministic address derivation: SHA256(owner || definition) → seed → AccountId
- Idempotent Create (no-op if ATA already exists)
Wallet CLI (`wallet ata`):
- `address` — derive ATA address locally (no network call)
- `create` — initialize an ATA on-chain
- `send` — transfer tokens from owner's ATA to a recipient
- `burn` — burn tokens from owner's ATA
- `list` — query ATAs across multiple token definitions
Usage:
wallet deploy-program artifacts/program_methods/associated_token_account.bin
wallet ata address --owner <ID> --token-definition <DEF_ID>
wallet ata create --owner Public/<ID> --token-definition <DEF_ID>
wallet ata send --from Public/<ID> --token-definition <DEF_ID> --to <RECIPIENT> --amount 100
wallet ata burn --holder Public/<ID> --token-definition <DEF_ID> --amount 50
wallet ata list --owner <ID> --token-definition <DEF1> <DEF2>

Following the work done in
https://github.com/logos-blockchain/lssa/pull/292 and the comment on
extending the work
https://github.com/logos-blockchain/lssa/pull/292#pullrequestreview-3672282664,
this commit introduces a new `--label` option to the `wallet account
new` sub command.
**Usage**:
```
wallet account new public --label "Public test account"
wallet account new private --label "Private test account"
```
Labels have to be unique across all accounts in the wallet storage.
The commit also adds tests, which make use of the `WalletSubCommand`
trait functions (hence the change to make it a `pub trait`).
