Add /api/cron/compute-venue-calibration endpoint
On-demand endpoint (no schedule) to compute league-specific venue calibration for v3 Sofascore xG. Runs on main server where sofascore_xg and derived v3 cache both live. Trigger manually with CRON_SECRET when needed.

Writes to data/xg-model/venue-calibration-v3.json with per-league home/away factors. Also computes FotMob baseline for comparison.
Note: cloud-lab doesn't have DB access, so this runs on the web container (same container that handles /api/cron/accumulate-xg).
