[BUG] Issue moving tokens (eg: st.FLOW and USDC.e) between Cadence / EVM at max precision

[JeffreyDoyle]

Current Behavior

• Users are reporting issues moving st.FLOW from their COA account to their Cadence account in Flow Wallet. The issue isn't happening when attempting to send these tokens between the accounts, but does happen when using our move feature. The issue comes up when attempting to move using greater precision (number of decimal places) than is supported.

Expected Behavior

• Users are able to move st.FLOW / USDC.e (and any other token) between their COA and their Cadence account in Flow Wallet, using the maximum supported precision.

Steps to Reproduce

• Acquire some st.FLOW in a COA in Flow Wallet
• Attempt to move that st.FLOW to your Cadence account using the maximum supported precision.
• Observe the transaction error.

Expected Outcomes

• Users are able to move st.FLOW / USDC.e (and any other token) between their COA and their Cadence account in Flow Wallet, using the maximum supported precision.

Platforms

• Extension
• iOS (Reported on iOS, but let's verify all platforms)
• Android

@Peppermint1020 - This occurs when inputting more than the supported decimal places for the amount of token to move. We need to ensure we properly round the amount to the correct precision.
