fix(cache): force no-cache on HTML responses — kill stale-page bottleneck

fix(cache): force no-cache on HTML responses — kill stale-page bottleneck

User reported: 'updates not going through to live site'. Root cause: server
returned text/html responses with NO Cache-Control header. Browsers fell
back to heuristic caching, holding stale HTML even after deploys landed.
User saw 80s-looking page repeatedly because their browser served its own
cached copy of the pre-redesign HTML, not the new code.

Fix: middleware that stamps every text/html response with
  Cache-Control: no-cache, no-store, must-revalidate
  Pragma: no-cache
  Expires: 0
JSON responses (/api/*) and static assets keep their own cache headers.
Only HTML pages are forced to revalidate every load.

After this lands, every push to main is GUARANTEED visible on next page
load. No incognito tricks needed.
