Marc-André Bombeck 13f8905ea1 perf(insights): skip heavy live aggregate when rollups are populated ...

v1.4.35 left the regression intact: comprehensive-aggregator and the
slim summaries slice still ran the full COUNT/MIN/MAX/AVG `$queryRaw`
in parallel with the rollup read, only preferring the bucket-derived
values when the count happened to match. Net round-trip count saved
was zero on Marc's 311k-row account.

Promote the rollup table to the canonical source on the happy path:
gate on a cheap `SELECT COUNT(*) FROM measurement_rollups` and, when
non-zero, drop the heavy aggregate. The bucket composition feeds
count/min/max/mean, a narrow `$queryRaw` keeps the non-composable
windowed columns (stddev/anomalies/avg7/avg30/avg30_last_month + the
three slope tuples), and the legacy heavy aggregate stays as the
cold-mount fallback for accounts whose backfill is mid-flight.

Unit tests pin the contract: the heavy aggregate is NOT called on the
rollup-fresh branch. Integration test verifies byte-identical count /
min / max / mean against a parallel live SQL pass on a populated
fixture.
