refactor: wrap all errors in ConvexError

- Update error() helper to throw ConvexError instead of plain objects
- Add isApplicationConvexError() type guard for client-side error checking
- Fix Vite config to include convex/values in optimizeDeps for proper instanceof checks
- Update error handling to check ConvexError wrapper and extract data property

This ensures all application errors are properly typed and can be identified
using instanceof ConvexError on the client side.
