pgx binds a nil Go slice as SQL NULL, which bypasses the column's '{}'
default and violates its NOT NULL constraint, so reports without
playback session ids failed to insert. Bind an empty slice instead.
The ingest path also swallowed the underlying insert and bundle
validation errors, logging only a generic rejection reason; both sites
now log the real error so failures are diagnosable from server logs.

Implements slice 1 of docs/design/2026-07-19-client-diagnostics.md: the
versioned contract (schemas, fixtures, Go validator), storage-validated
diagnostics.uploads_enabled gate, account-scoped status endpoint, hardened
streaming multipart ingest with quota reservation and a receiving/ready/
failed report state machine, S3 streaming puts, acting-admin report API
(list/detail/download/delete with audit events), and the retention +
orphan-reconciliation cleanup task.
