feat(sys-ctl-hlth-csp): add support for ignoring network block domains

Introduced new variable HEALTH_CSP_IGNORE_NETWORK_BLOCKS_FROM (list, default [])
to suppress network block reports (e.g., ORB) from specific external domains.
Updated script.py to accept and forward the flag, extended systemd exec command
in tasks, added defaults, and documented usage in README.

 - **Domain Extraction:** Parses all `.conf` files in the NGINX config folder to determine the list of domains to check.
 - **Automated Execution:** Registers a systemd service and timer for recurring health checks.
 - **Error Notification:** Integrates with `sys-ctl-alm-compose` for alerting on failure.

+### Variables
+
+- **`HEALTH_CSP_IGNORE_NETWORK_BLOCKS_FROM`** (list, default: `[]`)  
+  Optional list of domains whose network block failures (e.g., ORB) should be ignored during CSP checks.
+
+Example:
+
+```yaml
+HEALTH_CSP_IGNORE_NETWORK_BLOCKS_FROM:
+  - pxscdn.com
+  - cdn.example.org
+```
+
+This will run the CSP checker with:
+
+```bash
+checkcsp start --short --ignore-network-blocks-from pxscdn.com cdn.example.org <domains...>
+```
+
+### Systemd Integration
+
+The role configures a systemd service and timer which executes the CSP crawler periodically against all NGINX domains.
