fix(o11y): promote all tag_filterlist telemetry counters to INFO level (#1822)

## Summary

Promotes all five `TagFilterlist` transform counters from debug level to INFO level so they are visible in production. Three of these (`rule_hits_total`, `rule_misses_total`, `tags_filtered_total`) are referenced in the tag filtering dashboard. The remaining two (`noop_hits_total`, `metrics_modified_total`) provide useful signal for understanding filter effectiveness and are promoted for consistency.

## Test plan

- [x] `cargo test -p agent-data-plane tag_filterlist` — all tests pass
