[Android] [ExecTx] Edit Transaction Fee Screen

[elgatovital]

The screen gives user a way to change the fee-related parameters of the transaction to some manual values instead of using automatically estimated values.

The actual fields depend on the transaction type which depends on the supported transaction type of the chain (Chain Info -> features -> EIP-1559)

Figma iOS

• Legacy Transaction type
  • Nonce
