fix: update component and import paths

Changes:
- Update font-awesome component closing tag to match naming
- Change @capacitor/app import to use local wrapper
- Fix component self-closing tags in ContactScanView.vue

This improves consistency in component usage and centralizes
capacitor imports through our wrapper layer.
