Fix missing QR on every member page — blocked by our own CSP

The QR on /p/<id> and /p/<id>/<slug> was drawn by an inline <script>, but the
site sends `script-src 'self'` with no 'unsafe-inline'. The browser silently
refused to run it, so the QR box rendered as an empty white square on every
member page, not just Funnel Factory ones.

Moved the bootstrap to /page-qr.js and pass the link via a data attribute, so
no page data is interpolated into executable script and the CSP stays as
strict as it is. Loosening script-src to fix this would have traded a
site-wide security property for one widget.

This matters more than it looks: these pages go on printed flyers and ad
destinations, where an unscannable QR is discovered by the person holding the
paper.
