Increase timeout for WebSocket connection to Relayer in Payroll dev site

We need to increase the timeout for WebSocket connection to Relayer "http://dev-payroll.ligetron.com" site.

Taking "deploy-develop" branch from  "payrolls" repo as reference, on line:
https://github.com/ligeroinc/payrolls/blob/deploy-develop/public/assets/payroll_crypto.js#L1252
we need to replace 30000 with MAX_POLLING_WAIT_MS.
