Load Alpine's CSP build so the UI's directives run (closes #371)
Every page's Content-Security-Policy forbids eval, which the standard Alpine.js build needs, so no directive ran in a browser: both add forms on the webhook page showed open, and events in the event log could not be collapsed. The UI now loads Alpine's CSP build (@alpinejs/csp 3.14.9 in 3p/); the policy is unchanged. Each directive names a property or method of a component registered in static/js/app.js (collapsible, targetForm), and each card holds its own x-data. A browser test, built only with the browser tag, loads the webhook page and the event log under the real headers; make test-browser runs it in Docker. New test-only dependency chromedp, which raises golang.org/x/sys to 0.47.0.

# Browser test image, built by script/test-browser (make test-browser). It
# runs the test in internal/server that loads the pages in a headless
# browser under the real Content-Security-Policy. That test is built only
# with the browser build tag, so make test leaves it out. Here the browser
# comes from a digest-pinned image, and if it is missing the test fails.
