sys-svc-dns: add apex A/AAAA records for SYS_SVC_DNS_BASE_DOMAINS via task_include

Browse Source 
This update introduces apex (@) A and optional AAAA records for all base SLD domains.
The tasks were moved into a new 02_apex.yml file and are looped using
SYS_SVC_DNS_BASE_DOMAINS. CAA record loops were updated accordingly.

Bootstrap and maintain **DNS prerequisites** for your web stack on Cloudflare.
This role validates credentials and (by default) ensures:
- **Wildcard A/AAAA records** (`*.parent`) for parent hosts via `sys-dns-wildcards` (no base/apex records)
- **A (and optional AAAA) records** on the **apex** (`@`) for all **base SLD domains**
- **Wildcard A/AAAA records** (`*.parent`) for parent hosts via `sys-dns-wildcards`
- *(Optional)* **CAA** records for Let’s Encrypt (kept as a commented block you can re-enable)
Runs **once per play** and is safe to include in stacks that roll out many domains.

## What it does
1. **Validate `CLOUDFLARE_API_TOKEN`** is present (early fail if missing).
2. **Ensure wildcard parent DNS exists** (`*.parent` derived from children):
2. **Ensure apex A/AAAA exist** for every **base SLD** in `SYS_SVC_DNS_BASE_DOMAINS`:
- Writes `@ A` → `networks.internet.ip4`
- Writes `@ AAAA` → `networks.internet.ip6` (only if global and present)
3. *(Optional)* **CAA records** for all base SLDs (commented in the tasks; enable if you want CAA managed here).
4. **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).
> Parent hosts example:
> `c.wiki.example.com` → **parent** `wiki.example.com` (plus `example.com` apex)
