style: Improve code formatting and consistency

Code formatting improvements across multiple files:

1. databaseUtil.ts:
   - Convert single quotes to double quotes for string literals
   - Maintain consistency with project style guidelines

2. CapacitorPlatformService.ts:
   - Convert single quotes to double quotes for string literals
   - Align with TypeScript formatting standards

3. NewEditProjectView.vue:
   - Improve code formatting for error handling lambda
   - Better readability with proper line breaks and indentation

These changes improve code consistency and readability without
affecting functionality. All changes follow project style guidelines.
