kevinveenbirkenbachandClaude Opus 5.5 b358a8bb00 fix(web-app-keycloak): append the admin allowlist only when networks are declared
tasks/00_core.yml built webserver_extra_configuration by concatenating the
helper iframes, the admin allowlist and the logout panel template lookups
with `~`. With the shipped empty `services.keycloak.admin.allowed_networks`
the allowlist template rendered no text, Ansible's template lookup returned
None for it, and `~` wrote the word "None" into the auth vhost. OpenResty
then refused `unknown directive "Nonelocation"` in front of the logout
panel location and every deploy with Keycloak went red.

The role now resolves the declared networks once in KEYCLOAK_ADMIN_NETWORKS
and the task appends the allowlist template only when that list is not
empty, the same guard the logout panel uses. The template renders the
restricted /admin location unconditionally from KEYCLOAK_ADMIN_NETWORKS.

With a list that did not contain the deploy host, the deploy still went
red: Keycloak answers `/` with a redirect to `/admin/`, so the CSP health
check and the front proxy probe, which request `/` from the host, got 403
and hlth-csp failed. While the allowlist is active, `location = /` now
redirects to the account console of the platform realm instead, and the
README no longer claims the deploy needs no entry for any reason.

test_admin_allowlist.py rendered the template with plain Jinja, which
yields '' for an empty template, so it could not see the None. It now
evaluates the task's own webserver_extra_configuration expression through
Ansible's Templar and real template lookup, which reproduces
"HELPER_IFRAMES\nNoneLOGOUT_PANEL" on the old task, and covers the root
redirect.
