fix(docker): drop inherited VOLUME /srv/www that caused silent stale deploys

VOLUME ["/srv/www"] created an anonymous volume that docker compose reuses across
container recreation, shadowing a freshly COPY'd SPA bundle with the previous build
— up -d --build exited 0 while serving the old bundle (and poisoned the PWA service
worker's ngsw.json). A child image cannot un-declare an inherited VOLUME, so it must
not be declared: removing it makes the COPY case deterministic and leaves the runtime
bind-mount case unaffected. Also refreshed the README FROM tag v1.0.0 -> v1.6.0.

+### Fixed
+
+- **Dropped `VOLUME ["/srv/www"]` from the base image.** The declaration created an anonymous
+  volume at the SPA root that `docker compose up` reuses across container recreation, so a
+  rebuild silently kept serving the previous bundle (`up -d --build` exited 0 while shipping the
+  old build; on a PWA the stale `ngsw.json` then poisoned the service-worker cache). Consumers
+  could not un-declare an inherited `VOLUME` and were stuck with `--renew-anon-volumes` forever.
+  Removing it makes the headline `COPY dist/ /srv/www/` case deterministic, and the runtime
+  bind-mount case (`-v /path:/srv/www`) is unaffected. *The `v1.6.0` image was rebuilt and
+  re-pushed with this fix.* Consumers with an already-poisoned anonymous volume need a one-time
+  `-V` (or `docker volume rm`) to shed it.
