fix(landing): expose Prism globally before loading prism-sql

prismjs/components/prism-sql references the global Prism at module top level,
which is undefined under ESM. The manualChunks rule also stuffed core and the
language file into one chunk, so even a dynamic import would still trigger
prism-sql synchronously when vendor-prism evaluated. Import Prism as a value,
assign window.Prism, then dynamic-import prism-sql; split components out of
vendor-prism so the language chunk is only evaluated after the global is set.
This unblocks the inline module on Pages, where the ReferenceError was killing
the hero ER graph and every scroll-reveal animation.
