feat(web-app-wordpress): add idempotent single-site domain update via WP-CLI

- New task 04_update_domain.yml updates home/siteurl only when needed
- DB-wide search-replace (old → new), GUID-safe, precise, tables-with-prefix
- Normalizes http→https, strips trailing slashes, then flushes cache/rewrites
- Guarded by is_multisite()==0; multisite untouched
- Wired into main.yml with auto target URL via domains|get_url

Fixes post-domain-change mixed/CSP issues due to hard-coded old URLs.
