Replace konecty:mongo-counter with inline implementation

Remove the konecty:mongo-counter Meteor package dependency and replace
it with a minimal inline incrementCounter function using raw MongoDB
findOneAndUpdate. Also exports an async version for future Meteor 3.0
migration. No data migration needed — uses the same next_val field.
