Add pagination to "My Alerts"

[kryswisnaskas]

Add pagination to my activity reports alerts.

There is a sequelize bug that prevents successfully querying using limit and order. This ticket is to figure out if there is a workaround or another way of implementing pagination that works with sorting.

More information about the bug:
sequelize/sequelize#9869
