- Add scores for overloaded users, e.g. `(+25% avg)` which means the
user is scheduled to be on-call 25% more than average for given
schedule.
- Add score for gaps, e.g. `Schedule has gaps (29% not covered)` which
means 29% of time no one is scheduled to be on-call.
- Make things easier to understand when there are gaps in the schedule,
add `(see overloaded users)` text.
- Consider events for next 52 weeks (~1 year) instead of 90 days (~3
months), so the quality report is more accurate. Also treat any balance
quality >95% as perfectly balanced. These two changes (period change and
adding 95% threshold) should help eliminate false positives for _most_
schedules.
- Modify backend & frontend so the backend returns all necessary user
information to render without using the user store.
- Move quality report generation to `OnCallSchedule` model, add more
tests.

This change seems to have introduced some unexpected behavior with slack
user groups. Reverting to reproduce locally and push an improved update.
# What this PR does
Fixes slow internal`GET /schedules` endpoints. Using the fake-data
generation script in #1128, I generated 65 calendar schedules in my
local setup. This resulted in the following endpoint performance:

The responses which show ~76 queries were run on the latest `dev`
branch. Responses w/ ~26 queries were run on this branch.
Additionally:
- add typing to a few methods in `apps/schedules/ical_utils.py`
- document `apps/api/permissions/__init__.py:user_is_authorized`
function
