Add API support for new features

[brigleb]

There's now API support for:

• Timelines: account-wide and per-person progress reports
• Todo reports: assigned, overdue grouped by lateness
• Schedule upcoming events
• Check-in questions
• Dock tools and positioning

Which should we prioritize adding?

Todo reports would be amazing. My wishlist rank would be: Todo > Schedule > Timelines > Checkin > Dock
