CLI: add new --show option for miden-client tx

miden-client txis the only place where you can look at a transaction after it has been submitted, and it is only where you can track transaction from the CLI. It looks like:

ID | Status | Account ID | Script Root | Input Notes | Output Notes
-- | -- | -- | -- | -- | --
0x0c97... | Committed (Block: 52) | 0xb753... | 0x09e1... | 0 | 1
0xbdd8... | Pending | 0xb753... | 0x09e1... | 0 | 1

New tx --show <id> should print metadata about single transaction: transaction ID, status, account ID, script root, notes IDs, block number, block height, transaction status with the expiration block in case of "Pending" status, creation time, and the account state commitment before and after. A private note that isn't yours can't be resolved at all, instead of the ID we mark it as private.

查看現有的 `miden-client tx` 命令實作，以了解交易資料的擷取和顯示方式。新的 `--show ` 選項應擴展此功能，以輸出單一交易的詳細元資料。首先檢查 CLI 命令結構和交易資料模型，然後為指定欄位實作格式化。透過使用已知的交易 ID 執行命令進行測試。
