refactor: move lib directory to libs for consistency

- Move src/lib/capacitor to src/libs/capacitor
- Move src/lib/fontawesome.ts to src/libs/fontawesome.ts
- Update import paths in main.capacitor.ts and main.common.ts
- Remove empty src/lib directory

This change standardizes the project structure by using the 'libs'
directory consistently throughout the codebase.
