Bootcamp page: Reserve your seat now buys the bootcamp (product_id 12)

The three Reserve-your-seat CTAs posted to /support.html#contact. They now
run the same checkout path as the main page's Buy Now: a new page-local
static/buy.js mirrors script.js buyNow() (POST basket to
20.odoo4projects.com/shop/post_basket, clear=1, UTM cookies appended) and
binds .btn-buy via one delegated click handler. CTAs become
.btn-buy[data-id=12]; label unchanged. script.js and the homepage untouched.

The Price-and-booking section keeps a second, smaller link to
/support.html#contact so readers who have questions still have a fallback.
