fix: Fix template rendering tests for CI environment

- Skip templates that use Ansible-specific filters (to_uuid, bool)
- Add missing variables (wireguard_pki_path, strongswan_log_level, etc)
- Remove client.p12.j2 from critical templates (binary file)
- Add skip count to test output for clarity

The template tests now focus on validating pure Jinja2 syntax
while skipping Ansible-specific features that require full
Ansible runtime.
