Date.toLocaleString() is undefined

[gudnuf]

Seems that the add transaction call in one of

• createSendableToken - hooks/cashu/useCashu
• sendToMintlessUser - hooks/boardwalk/useMintlessMode
• payInvoice - hooks/cashu/useMintlessMode

are throwing an error on new Date().toLocaleString().

Should make sure this is always defined and move the new Date() logic to the HistorySlice

dispatch(
          addTransaction({
             type: 'ecash',
             transaction: {
                token: token,
                amount: -amount,
                unit: wallet.keys.unit === 'usd' ? 'usd' : 'sat',
                mint: wallet.mint.mintUrl,
                status: TxStatus.PENDING,
                date: new Date().toLocaleString(),
                pubkey: opts?.pubkey,
                gift: opts?.gift,
                fee: opts?.feeCents,
             },
          }),
       );
