Tenants extractor now partitions by ISO week (e.g. 2026/W09) instead of
month (2026/02), so each weekly run writes a fresh file rather than
skipping for the rest of the month.
_load_tenant_ids() in playtomic_availability already globs */*/tenants.jsonl.gz
and sorts reverse — 'W09' > '02' alphabetically so weekly files take priority
over old monthly ones automatically.
