[Cashtab] Update SendXec with direct calls to antd notifications
Summary:
This diff deprecates sendXecNotification and updates SendXec.js to call on the antd component directly.
Notification unit test already covered under SendXec.test.js' Clicking "Send" will send a valid tx with op_return_raw after entry of a valid address and bip21 query string with valid amount and op_return_raw params to Send To field test.
Test Plan:
- grep -r sendXecNotification src/ with no output
- npm test
- npm start
- success notif: send a one to one XEC tx (no change to notification UI)
- error notif: send a one to many XEC tx with an amount larger than balance
