Load Alpine's CSP build so the UI's directives run (closes #371)
check / check (push) Successful in 4m4s
Details

Browse Source 
The pages' Content-Security-Policy forbids eval, which the standard
Alpine.js build needs, so no directive ran: add forms showed open and
events never collapsed. 3p/ now holds the @alpinejs/csp 3.14.9 tarball
instead, and every directive in templates/ names a property or method
of a component registered in static/js/app.js, as that build requires.
The policy is unchanged.

A browser test in internal/server, 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, in a digest-pinned headless
browser image (Dockerfile.browser).

# 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.
