Addresses security concerns from OWASP audit and CodeQL by enforcing strict
host key verification and TLS certificate verification.
Security Changes:
- Enforced strict SSH host key checking in pkg/container and devops.
- Removed insecure SSH host key verification from pkg/ansible.
- Added synchronous host key discovery during VM boot using ssh-keyscan.
- Updated UniFi client to enforce TLS certificate verification by default.
- Added --insecure flag and config option for UniFi to allow opt-in to
skipping TLS verification for self-signed certificates.
CI and Maintenance:
- Fixed auto-merge workflow by providing repository context to 'gh' command.
- Resolved merge conflicts in .github/workflows/auto-merge.yml.
- Added unit tests for secured Ansible SSH client.
- Fixed formatting issues identified by QA checks.
