[PROTOTYPE - Invoke Contract] enable token units AND base units

[jeesunikim]

There are cases where SEP41 contracts' assets are hard to move because they often use a different set of decimal architectures. This PR is to alleviate the UX experience by querying the contract and adapt the 'amount' field to the specific asset architecture by using decimals() beforehand.

The pain points: To move SolvBTC and deJAAA in CC64WBDGS6QQP22QTTIACYIXT3WF7BBQEYOQPLTP7GTKYY7PZ74QYGSL,

• To move 5 SolvBTC, users have to put 500000000
• To move 5 deJAAA, users have to put 5000000000000000000

• Every function card passes a path-only ID such as amount, while InvokeContract mounts all function cards together. This gives the new radios duplicate IDs and the same name, so the browser treats transfer/approve/burn controls as one radio group; selecting one card can uncheck another, and labels may target the wrong control. Include the function name or another per-instance identifier in both the IDs and group name.
