fix(staging): enforce grain dedup in resources + opening_hours + skip old blob in tenants

Both stg_playtomic_resources and stg_playtomic_opening_hours lacked QUALIFY ROW_NUMBER()
dedup despite declaring a grain. When both tenants.json.gz (old) and tenants.jsonl.gz (new)
exist for the same month, the UNION ALL produced exactly 2× rows.

Fixes:
- stg_playtomic_resources: QUALIFY ROW_NUMBER() OVER (PARTITION BY tenant_id, resource_id)
- stg_playtomic_opening_hours: QUALIFY ROW_NUMBER() OVER (PARTITION BY tenant_id, day_of_week)
- playtomic_tenants.py: skip if old blob OR new JSONL already exists for the month,
  preventing same-month dual-format writes that trigger the duplicate

Row counts after fix: ~43.8K resources, ~93.4K opening_hours (was 87.6K, 186.8K).
