Reject non-integer weekday values in presence pattern requests

The create and edit pattern models typed weekday values as lax int, so
JSON true, "1" and 1.0 were coerced to weekday 1. Type them StrictInt
so each is a 422 naming the pattern field, and add create and edit
regression cases for bool, string, float and out-of-range weekdays.
