fix: disable multiple send transactions

[BZahory]

Description

Multiple transactions break STX logic; we need to prevent these transactions from being submitted concurrently. While the confirmations screen covers this, the swap+send flow bypasses this screen altogether, so we need to add logic to prevent submission via the instant submit button (i.e. submit for swap+send).

Manual testing steps

1. Submit a smart transactions (e.g., basic send on mainnet)
2. Go to the send flow and fill out the form for a swap+send
3. Ensure that the submit button is disabled with a tooltip: "A previous transaction is still being signed or submitted"
4. Ensure that the send flow is not reset to the recipient stage when the transactions complete
5. Ensure that a transaction can now be submitted as normal
