fix: remove duplicate cron schedules in CI/CD workflow

Remove duplicate cron entries that were preventing scheduled builds
from running. GitHub Actions silently ignores duplicate times.

Previous issues:
- Lines 6 and 14 both had '30 12 * * 1-5'
- Lines 8 and 15 both had '0 15 * * 1-5'

New schedule has 9 unique times covering both EST and CET working
hours with ~2.5 hour spacing to avoid build overlaps.
