Worked on the openwrt/luci repository to enhance the stability of the Tunnel/Remote configuration modal for VPN settings. Addressed a recurring crash by implementing robust handling of crypto_proposal sections and introducing safeguards against null or undefined MultiValue inputs, which previously led to UI rendering errors. Utilized JavaScript and front end development skills to filter proposals by ESP type and display appropriate placeholders when no valid options were available. This fix resolved LuCI issue #8606, resulting in a more reliable VPN configuration experience for users integrating Strongswan Swanctl, while also improving type-safety and resilience in the user interface components.
