Add per-PR frontend preview environments#102

Deploy an ephemeral preview of the web-client for PRs touching the frontend. On open/sync, the PR's web-client is built, pushed to GHCR, and deployed into a preview-pr-<N> namespace; the production backend is reused via a spring-api ExternalName alias, so it's one ~50m/64Mi pod against real data. A sticky comment posts the per-PR URL (wildcard DNS + per-host Let's Encrypt). The namespace is torn down when the PR is closed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The AET cluster token is namespace-scoped and cannot create namespaces, so the per-PR-namespace approach failed with a Forbidden error. Deploy preview resources into the existing `app` namespace instead, named/labelled per PR (web-client-pr-<N>, preview-pr=<N>). The production spring-api Service is already in this namespace, so the web-client's nginx proxy reaches it directly and the ExternalName alias is dropped. Teardown deletes by the preview-pr label.

The deploy step captures the script's stdout into a step output; kubectl's "... created" lines made it multi-line and broke the key=value GITHUB_OUTPUT format. Route command output to stderr (still shown in logs) and write only the URL to fd 3 / stdout. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Spins up a live preview of the web-client for every PR that touches the frontend, so reviewers get a clickable link.
