chore(deps): upgrade Next/React ecosystem, sync lockfile, and add CI/docker configs

- bump next to 16.0.0, react/react-dom to 19.2.0 and update related deps (react-day-picker, react-hook-form, zod, lightningcss, scheduler, typescript, @types/*, tailwind tooling, etc.) in package.json and bun.lock
- add overrides for @types/react and @types/react-dom
- remove --turbopack flags from package.json scripts and configure turbopack root in next.config.ts
- tighten tsconfig (jsx -> react-jsx, include extra .next dev types, formatting)
- add GitHub Actions workflow for Docker build/push (.github/workflows/main.yml)
- add Dockerfile and compose.yml for building/running containerized app

.github/workflows/main.yml
