feat: require pagination proof for reconciliation inventory claims (Closes #308)

Add assess_reconciliation_inventory_proof to review_proofs:
already-landed reconciliation reports may not claim a complete queue
scan or that all already-landed PRs were found unless the report
carries the pagination proof fields (Requested page size, Pages
fetched, Returned PR count per page, Final page proof) and the
per-page gitea_list_prs pagination metadata proves the final page was
reached — inventory_complete, is_final_page with has_more=false, or a
returned count below the requested page size. Declared page counts and
per-page counts must match the evidence. Reports without a
completeness claim pass without proof. Fails closed on missing
evidence or malformed page metadata. Tests cover first page below
limit, first page exactly at the page limit, multi-page traversal to
the final page, missing pagination metadata, missing report fields,
page-count and per-page-count mismatches, and the no-claim case.
