Missing loading state when submitting revenue transaction causes duplicate submissions

[woydarko]

Bug Description

The "Record Revenue" button does not get disabled while a transaction is being processed. This allows users to click the button multiple times rapidly, potentially sending duplicate revenue recording transactions to the smart contract.

Steps to Reproduce

1. Connect wallet with a registered Business Object
2. Enter a revenue amount in the input field
3. Click "Record Revenue" button quickly multiple times before the transaction confirmation appears
4. Check IOTA Explorer for the wallet's transaction history

Expected Behavior

The submit button should be disabled and show a loading indicator immediately after the first click, preventing any additional clicks until the transaction either confirms or fails.

Actual Behavior

The button remains clickable throughout the entire transaction signing and broadcasting process. Fast clicking sends multiple identical transactions, each recording the same revenue amount separately on-chain.

Impact

Users could accidentally inflate their revenue figures on-chain, corrupting their credit history data which is the core value proposition of Kredith.
