web-wallet: Warn Users About Sending Funds to Their Own Account in Send Flow

[nortonandreev]

Description

Following rusk issue #2959, we need to implement similar functionality in the Web Wallet. Specifically, in the Send flow, if a user attempts to send funds to their own account's moonlight address, the following should occur:

• Display a warning message informing the user that gas will be deducted for such a transaction.
• Optionally, provide an opportunity to redirect the user to the Allocate flow. However, as this does not avoid gas fees, its utility may be limited.

Scope of Work

• Warning Message: Add a clear warning when users attempt to send funds to their own moonlight address. The message should explain that gas fees will still apply.
• Optional Redirect: Consider adding an option to redirect users to the Allocate flow. Clearly explain the implications, i.e., that this will not avoid gas fees.
• Validation Logic: Update the Send flow to include a check for self-referential transactions involving moonlight addresses.

User Experience Goals

• Prevent confusion or unintended behavior when users send funds to their own account.
• Clearly inform users about gas fees associated with such transactions.

Tasks

1. Identify where in the Send flow validation the moonlight address check should be implemented.
2. Display a warning message if the destination address matches the user's own moonlight address.
3. Optionally, implement a redirection to the Allocate flow, ensuring users understand its implications.
4. Test thoroughly to ensure correct behavior and no regressions.
