Migrate frontend to TypeScript and extend user profile

Converted frontend codebase from JavaScript to TypeScript, including pages, components, and context. Added new layout and UI kit components. Updated backend user model and schemas to support profile fields (firstname, lastname, age, gender, height, weight, unit_preference) and added endpoints for reading/updating current user. Introduced food log listing endpoint and migration script for user table. Updated dependencies and build configs for TypeScript and Tailwind v4.
