resumeCampaign only updated status/pause_reason, so a campaign auto-paused
for many days and then resumed could immediately satisfy
escalateWeeklyLimits' 7-day check and double its daily limit right after
coming back from an unhealthy state -- the opposite of the intended
safety behavior. Now resumeCampaign also stamps semana_iniciada_em to
datetime('now'), resetting the weekly clock on every resume.
