New endpoints added for managing pending reading changesets: GET /v1/metering/reading/{meter_id}/{counter_id}/changesets (list pending), PATCH /v1/metering/reading/{meter_id}/{counter_id}/changesets/{changeset_id} (edit the proposed value), POST .../changesets/{changeset_id}:apply (approve and commit to ClickHouse), and POST .../changesets/{changeset_id}:dismiss (reject)
New optional direct query parameter added to all reading-write endpoints (POST /v1/metering/reading, POST /v1/metering/readings, POST /v1/metering/readings/{meter_id}, POST /v2/metering/readings) — when true, bypasses changeset interception and writes directly to ClickHouse, auto-clearing matching pending changesets; the same effect is triggered automatically when source: 'ERP' is set in the request body
New optional include_pending_changesets query parameter added to GET /v1/metering/meter and GET /v1/metering/reading/{meter_id}/{counter_id}, including pending reading changesets in the response alongside confirmed readings
