feat(lint): derive container paths from meta/volumes.yml everywhere

meta/volumes.yml says where a volume lands inside its container. Wherever a
second file spelled the same path out, the two drifted independently: the mount
moves, the consumer keeps pointing at the old place, and nothing fails until the
process looks for content that is not there. e031b7f61 fixed exactly this for
web-app-moodle; this generalises it and makes the rule hold.

The lookup gains what a caller needs. `targets` maps each mounting service to
its container path, and `target` is the one path an entry mounts at -- present
only when every mount agrees. An entry that lands at different paths per service
omits `target` rather than picking one, and the caller names the service:

    "{{ lookup('volume', application_id, 'prometheus_config').target }}"
    "{{ lookup('volume', 'web-app-prometheus', 'host_sys').targets['node-exporter'] }}"

66 literals across 48 role files now derive. Replacement only happened where the
path stood alone -- /srv/app inside /srv/app/data is a different path -- and
every rewritten file was re-parsed, Jinja and YAML alike. Three sites the tool
refused rather than guess were done by hand: zammad's path sat in a Jinja list
literal, seaweedfs' inside a quoted string feeding a filter, and openresty's
/var/run/docker.sock is not a mount target at all but the socket on the host,
which only happens to spell the same string. That one carries the single
nocheck.

tests/lint/repository/spot/test_volumes_path_single_spot.py keeps it that way.
roles/*/files/ is out of scope by construction: it is copied verbatim into an
image and executed there, so a Dockerfile or entrypoint has no Ansible to
evaluate a lookup with.

One defect this found, and it was in the tooling rather than the roles: deciding
ambiguity AFTER filtering short paths made web-app-prometheus' host_sys look
single-valued -- it mounts /sys for cadvisor and /host/sys for node-exporter,
and /sys is below the length filter. The template would have rendered an
undefined `.target`. Both the converter and the rule now decide ambiguity over
every target and filter afterwards, and that call reads targets['node-exporter'].

Verified by resolving rather than by reading: all 70 accesses in the diff were
run against the real registry and every one yields a non-empty path equal to the
literal it replaced. make test-lint: 328 passed.

Not verified: no Ansible render, so a call site whose surrounding context cannot
build the applications registry would still fail at deploy.

+"""Forbid repeating a container path that ``meta/volumes.yml`` already declares.
+
+``meta/volumes.yml`` says where a volume lands inside its container. Once a
+second file spells the same path out, the two drift independently: the mount
+moves, the consumer keeps pointing at the old place, and nothing fails until
+the process looks for content that is not there.
+
+The registry is readable, so a role derives instead of repeating:
+
+    PROMETHEUS_CONFIG_FILE: "{{ lookup('volume', application_id, 'prometheus_config').target }}"
+
+``target`` exists when every mount of that entry agrees; an entry that lands at
+different paths per service exposes ``targets[service]`` instead.
+
+Scope: role files Ansible renders -- ``vars/``, ``tasks/``, ``templates/`` and
+the rest of ``meta/``. Two areas are out by construction:
+
+* ``roles/*/files/`` is copied verbatim into an image and executed there, with
+  no Ansible in sight, so a Dockerfile or an entrypoint cannot evaluate a
+  lookup. Those sites carry a per-line opt-out instead.
+* ``.md`` documentation names paths in prose.
+
+A path is only flagged where it stands alone; ``/srv/app`` inside ``/srv/app/data``
+is a different path and is left untouched.
+
+Per-line opt-out: ``# nocheck: volumes-path-single-spot`` on the offending line
+or the immediately preceding non-empty line, with the reason it cannot derive.
