Add missing install/uninstall scripts to Docker image and release builds (related to #644)

The Dockerfile and build-release.sh were missing several installer and uninstaller
scripts that the router expects to serve via HTTP endpoints:
- install-container-agent.sh
- install-host-agent.ps1
- uninstall-host-agent.sh
- uninstall-host-agent.ps1

This caused 404 errors when users attempted to add Docker/Podman hosts or use the
PowerShell installer, as reported in #644.

Changes:
- Dockerfile: Added missing scripts to /opt/pulse/scripts/ with proper permissions
- build-release.sh: Added missing scripts to both per-platform and universal tarballs
  to ensure bare-metal deployments serve the same endpoints as Docker deployments
