Follow-up to #6518 (issue #6480) addressing three review findings: - Document and lock in arrears semantics for the wallet Reserve top-up: when an auto-group retry lands on a more expensive group, the full reservation delta is deducted unconditionally (balance may go negative), mirroring settlement, so the logged pre-consumed quota always reconciles with the actual balance movement. Genuine DB errors still fail the attempt with update_data_error. Subscription funding keeps its insufficient-quota behavior: subscriptions enforce a hard used<=total cap and do not support arrears. - PriceData.FreeModel is cleared when a retry switches from a free group to a paid one, keeping it consistent with the billing session created at that point. - getChannel refreshes GroupRatioInfo only after channel selection succeeds, and the retry loop records the channel in use_channel before PrepareTieredBillingForSelectedGroup can fail.
