WIP: Convert min stake and max stake values in zwalletcli to ZCN ,mZCN and other formats

Hello @vudn95 here is a sample output for `./zwallet mn-info` command.

```

Here min_stake and max_stake values have to be converted into ZCN and other formats
Also, in any other places or responses or flags in zwalletcli where these value types are used,they have to be converted to ZCN and other formats.

the value conversion table is as follows:
1 ZCN = 1,000 mZCN = 1,000,000 µZCN
0.1 ZCN = 100 mZCN = 100,000 µZCN
0.01 ZCN = 10 mZCN = 10,000 µZCN
0.001 ZCN = 1 mZCN = 1,000 µZCN
0.0001 ZCN = 0.1 mZCN = 100 µZCN
0.00001 ZCN = 0.01 mZCN = 10 µZCN
0.000001 ZCN = 0.001 mZCN = 1 µZCN
0.0000001 ZCN = 0.0001 mZCN = 0.1 µZCN
0.00000001 ZCN = 0.00001 mZCN = 0.01 µZCN
0.000000001 ZCN = 0.000001 mZCN = 0.001 µZCN
0.0000000001 ZCN = 0.0000001 mZCN = 0.0001 µZCN = 1 sas (Saswata, smallest unit, nickname) (edited)

Esamina la codebase di zwalletcli per individuare dove vengono visualizzati i valori di min_stake e max_stake, ad esempio nell'output del comando mn-info. Identifica le strutture dati e le funzioni di formattazione. Implementa una funzione di conversione che trasformi i valori interi grezzi nei formati ZCN, mZCN e µZCN in base alla tabella di conversione fornita. Testa eseguendo i comandi di zwalletcli per assicurarti che i nuovi formati vengano visualizzati correttamente.
