test(calendar): pin the clock for the Paris today marker

The test of the today marker read the wall clock, so it only exercised
the Paris/local date mismatch between 22:00 and 24:00 UTC and passed
with or without the fix the rest of the day. Pin the clock to 22:16 UTC,
already the next day in Paris, so a UTC runner fails without the fix at
any time.

 bundle never changes, so ratios stay comparable with the recorded history; the

 Each scenario's budget is its multiplier times that calibration; the mean
 `planningMs` of its two measured repetitions must not exceed it. A scenario
 without a multiplier fails too. #286 tightened the multipliers once #302 met
