fix(web): render content pages dynamically so next build needs no DB

The home, doc, and search pages queried Postgres during SSG/static data
collection, so 'next build' failed in CI (no DB). Mark them
force-dynamic (and drop generateStaticParams from the doc page) so they
render at request time — instant at this corpus scale and build-safe
without a live database.
