fix: add libhdf5-dev for PyTables; harden pip install against missing packages

- Dockerfile: add libhdf5-dev to apt packages (required by the 'tables'
  PyTables package to compile its C extension)
- on-create.sh: bulk uv pip install now falls back to per-package install
  if any package fails (e.g. lsp/json-lsp/yaml-lsp may not resolve on
  PyPI); failed packages are logged but don't abort the prebuild
