fix: SSL Labs timeout + Lighthouse score variance

SSL Labs: switch from startNew=on to fromCache=on (maxAge=24h) so on-push
audits return a cached result in seconds instead of triggering a fresh 5-min
scan that times out before the 15-attempt limit. Fresh scans still happen on
the weekly schedule when the cache is cold.

Lighthouse: increase numberOfRuns 1→3. With aggregationMethod: optimistic,
LHCI takes the best of 3 runs, eliminating false-low scores from network
jitter in GitHub Actions runners (observed swings from 49 to 99 between runs).
