Fix empty Top locations table on high-cardinality sites, force ASN to string
- loki-config.yml: raise limits_config.max_query_series from Loki's
default (500) to 5000.
sum by (request_uri) (...)-style panel queries materialize one series per distinct URI before topk() can trim it, so any site with 500+ distinct URIs in the window silently came back empty instead of erroring. - Top ASN: force the ASN column to string via convertFieldType. It's a categorical identifier, not a quantity, and Grafana was likely auto-inferring it as numeric - which may also be why ad hoc filtering only works on ASN org and not ASN number.
