feat(nginx): renumber template includes and glob env overlays

Shift core-works-redirects to 30- and hastac-redirects to 40- so the
include order in the hcommons server block reads top-to-bottom:
buddypress (20), env overlay (25*), core-works (30), redirects (40).
Update nginx.conf and the hcommons/hastac-org templates to match.

The hcommons template now globs 25*.conf so env-specific overlays
slot in by filename without further edits; the dev overlay renames
to 25-buddypress-redirects.conf.template to reflect its actual role.
