User assignments and sign-ups, "My Todo" ✊

[richardolsson]

Description

A user should be able to find all the things that they are currently assigned in a single place. This includes call assignments, events that they have signed up for or otherwise been booked on, and tasks.

See epic #1615 for context.

Estimated size (S, M, L)

I think this issue is medium because the page and it's layout should be very simple, but it requires retrieving data from several different endpoints and presenting it side-by-side. The "tasks" feature has never been implemented in the Activist Portal before.

Prerequisites

None

Requirements

• Build "My todo list" at /my/todo
• List all current call assignments for the user
• List all upcoming events that the user has signed up for or been booked on
• List all tasks that the user has been assigned

Possible implementations

Maybe reuse event components from #1616.

Design specifications

Design will be developed along with the functionality, but the old Gen2 interface can hopefully be inspiring.

• The design should be mobile-first
• This page will replace the "My actions" and "Call assignments" sections at http://www.dev.zetkin.org/dashboard

Branch off the base branch called epic-1615/activist-portal-base (PR #1623) when working on this at the Code Camp.
