Native merchant reports

config.rs validates the shared HTTP/MCP query and private report layouts. period.rs resolves calendar windows in an IANA timezone and bounds chart points. source.sql reads immutable order money, original cart channels and provider refunds; sales.sql returns bounded summaries, buckets, channel ranks and product ranks. traffic.rs reuses the behavior owner's exact eligible SQL and inherited legal policy resolver; traffic.sql counts consented cart contexts, never API requests or people. There is no new tracking identity, event ledger, table or worker.

The parent module admits current reporting rights and projects optional product, channel-name and visitor fields by their existing domain permissions. Operational sales/visits remain in their environment. Saved presentation preferences stay in the existing personal live-shop workspace and never become release units.
