fix(05-01): switch Vite alias to array syntax with RegExp find pattern

- Replace object alias syntax with array of {find, replacement} entries
- '@' and 'lexical' aliases preserved as string find entries
- OnboardingWizard alias uses RegExp /^\.\/components\/OnboardingWizard$/ find
- RegExp matches raw import specifier from App.tsx in both dev and prod modes
