chore(docker): clear most CVEs in published image (npm/pnpm/uuid + drop curl) (#7674)

* chore(docker): clear most CVEs in published image — npm/pnpm/uuid + drop curl

Cuts published-image vulnerabilities from 18 (4H/13M/1L) across 8 packages
to 12 (2H/9M/1L) across 3 packages. The remaining three (curl/libcurl,
git, busybox) are all upstream Alpine 3.23 packages with "not fixed"
status — libcurl is pulled in transitively by git and cannot be
removed independently.

Changes:

- Provision pnpm via corepack instead of `npm install -g pnpm`, then
  remove the bundled npm. The base image's npm@10.9.7 ships old
  transitives (picomatch 4.0.3 → CVE-2026-33671/33672, brace-expansion
  2.0.2 → CVE-2026-33750) that we don't otherwise need at runtime;
  corepack handles pnpm directly without npm. Fixes 1H + 1M.

- Bump PnpmVersion 10.28.2 → 10.33.2 to align with the rest of the
  workflow and pull in pnpm's patched bundled brace-expansion (5.0.5
  vs 5.0.4). Fixes 1M.

- Add `uuid@<14.0.0` → `>=14.0.0` to pnpm.overrides
  (GHSA-w5hq-g745-h8pq). Fixes 1M.

- Drop `curl` from the runtime apk add list and switch HEALTHCHECK to
  wget (busybox built-in). curl was only invoked by the healthcheck and
  by dev/CI scripts that don't run in the container. Removes the curl
  CLI binary; libcurl remains as a git transitive dep, so the
  `apk/alpine/curl` advisories scout reports against libcurl persist
  but aren't reachable from any code we ship. As a side-effect this
  also clears nghttp2 (CVE-2026-27135) which was a curl-CLI dep.

- Switch HEALTHCHECK URL from `localhost` to `127.0.0.1` — alpine/musl
  resolves localhost to ::1 first and Etherpad only binds IPv4.

Verified locally: docker build → docker run → healthy → docker scout
cves shows 12 CVEs / 3 packages.

* fix(docker): refresh corepack before preparing pnpm (Qodo)

Node 22's bundled corepack ships a stale signing-key list and can reject
newer pnpm releases (nodejs/corepack#612), which would fail the image
build at `corepack prepare`. Mirror the snap/snapcraft.yaml workaround:
`npm install -g corepack@latest` before activating pnpm, in both
adminbuild and build stages. npm is still removed afterwards.

* docs(changelog): note docker image dropping curl/npm/npx (Qodo)

Address Qodo's "backwards-incompatible change without mitigation" rule
violations by documenting the removal in the 2.7.3 breaking-changes
section. Operators who exec into the container can apk add curl on
demand or use the busybox wget / pnpm already present.
