build: update Dockerfile for TypeScript compilation

- Add npm run build:ts step to compile TypeScript
- Copy web/ directory instead of cmd/server/static/
- Build pipeline now: Go deps → CSS → HTMX → TypeScript → Go binary
- TypeScript compiles to JavaScript before final image build

Integrates TypeScript compilation into container build process.
