Subject: [PATCH] chore: upgrade Loki 2.9.0 to 3.6.1 with tsdb/v13 schema (refs
 #98)

- Update Loki image from 2.9.0 to 3.6.1 in docker-compose.yml
- Migrate schema from v11 to v13, store from boltdb-shipper to tsdb
- Update storage_config to use tsdb_shipper with new index paths
- Remove deprecated shared_store config (removed in Loki 3.0)
- Disable structured metadata (not needed for current setup)
- Preserve 30-day retention policy (720h)
