Pull request overview

This PR addresses eslint issues in demo applications by fixing two types of violations:

1. Vue component props: Making props optional to align with TypeScript and Vue best practices
2. Angular error handling: Changing throw statements to use Error objects instead of string literals
3. Code formatting: Fixing spacing in type annotations

Changes:

• Made Vue component props optional (adding ? suffix) while ensuring default values are provided via withDefaults()
• Updated Angular error handlers to throw Error objects (throw new Error(...)) instead of string literals (throw '...')
• Fixed spacing in a TypeScript type annotation
