- Removes GetManagedAgentCount query - Adds new table `usage_events_daily` which stores aggregated usage events by the type and UTC day - Adds trigger to update the values in this table when a new row is inserted into `usage_events` - Adds a migration that adds `usage_events_daily` rows for existing data in `usage_events` - Adds tests for the trigger - Adds tests for the backfill query in the migration Since the `usage_events` table is unreleased currently, this migration will do nothing on real deployments and will only affect preview deployments such as dogfood. Closes https://github.com/coder/internal/issues/943
