fix: simplify Docker build workflow, remove PREBUILT artifact workaround

- Remove UI build artifact upload/download steps (18 lines removed)
- Remove .dockerignore manipulation workaround
- Always build UI from source inside Docker (more reliable)
- Remove PREBUILT arg from ui/Dockerfile and docker-bake.hcl

This fixes the '/app/build not found' error in CI by eliminating the fragile
artifact-passing mechanism. UI now builds fresh in Docker using build cache,
same as local development.
