upgrade: adopt V8.33.1 — final merge, our patches upstreamed natively

V8.33.0 absorbed our entire platform patch set as native features
(discovery/env_for macro override/blocks.css priority/type-mapping fix/
frontend entries/locale override) and synced trade-pro from our remote;
V8.33.1 adds HESU PIPE industrial-theme home fixes (1.3.1).

Zero patch re-application this round — all verified native. Theme
suites 35/35; full run 428 passed + same 10 known Windows env fails
(FAILED set unchanged). Live: container 8.33.1-dev.1 healthy, hesupipe
192 entries intact, trade-pro build 203 pages 0 errors.

Patch registry retired to archive — future upgrades are plain overlay.
