fix: Permit message, dataTree value incorrectly using default ERC20 decimals for non-ERC20 token values

[digiwand]

Description

Removes bug where fetchErc20Decimals was used in ui/pages/confirmations/components/confirm/info/typed-sign/typed-sign.tsx info component and passed to the message dataTree to be used. fetchErc20Decimals was incorrectly used as it cannot be assumed that the token contract is an ERC20 standard. Fixed by calling useGetTokenStandardAndDetails instead which will use the default 18 decimals digit if the standard is an ERC20 token with no decimals found in the details.

Related issues

Fixes: #28118

Manual testing steps

1. Go to test-dapp
2. Test Permit button
3. Observe both the simulation and message value display "3,000" (contract is not an ERC20 standard so it does not apply default 18 decimals)
