refactor(dns): replace sys-dns-parent-hosts with sys-dns-wildcards; emit only *.parent wildcards from CURRENT_PLAY_DOMAINS_ALL

Browse Source 
Rename filter parent_build_records→wildcard_records; create only wildcard (*.parent) A/AAAA records (no base/apex); switch to CURRENT_PLAY_DOMAINS_ALL; update vars to SYN_DNS_WILDCARD_RECORDS; adjust role/task names, defaults, and docs; add unittest expecting *.a.b from www.a.b.example.com.

Bootstrap and maintain **DNS prerequisites** for your web stack on Cloudflare.
This role validates credentials and (by default) ensures:
- **Parent host A/AAAA records** (incl. the **apex** SLD.TLD) via `sys-dns-parent-hosts`
- **Wildcard A/AAAA records** (`*.parent`) for parent hosts via `sys-dns-wildcards` (no base/apex records)
- *(Optional)* **CAA** records for Let’s Encrypt (kept as a commented block you can re-enable)

## What it does
1. **Validate `CLOUDFLARE_API_TOKEN`** is present (early fail if missing).
2. **Ensure parent DNS exists** (apex + “parent” FQDNs derived from children):
- Delegates to [`sys-dns-parent-hosts`](../sys-dns-parent-hosts/README.md)
- Creates A (and AAAA if enabled upstream) on the Cloudflare zone, optionally proxied.
2. **Ensure wildcard parent DNS exists** (`*.parent` derived from children):
- Delegates to [`sys-dns-wildcards`](../sys-dns-wildcards/README.md)
- Creates `A` (and `AAAA` if enabled) wildcard records on the Cloudflare zone, optionally proxied.
3. *(Optional)* **CAA records** for all base SLDs (commented in the tasks; enable if you want CAA managed here).
