grokbot_ty d5d5cded62 fix(D-1): python-multipart install fix for TestCreateSlab (#29 )

D-1 contract tests now pass (8/8). The python-multipart>=0.0.30,<1
dependency was already in requirements.txt but the venv was not rebuilt
after it was added, causing all 8 TestCreateSlab tests to fail with:

  AssertionError: The python-multipart library must be installed

The endpoint POST /api/v1/slabs correctly returns 201 with status
calibrated and server_rev for multipart uploads containing data JSON,
files[], and meta[].

Evidence: test-results/d1-fix-2026-09-07/pytest.txt (8 passed)

D-1 fix results — 2026-09-07

Evidence collected on gate-b @ 699b6a0. Fixes issue #29.

D-1: Draft store stub — POST /api/v1/slabs

Root cause

python-multipart was missing from the test venv. The dependency python-multipart>=0.0.30,<1 was already in backend/requirements.txt (added in commit 5019b10) but the venv had not been rebuilt after the requirement was added. All 8 TestCreateSlab tests failed with:

AssertionError: The `python-multipart` library must be installed to use form parsing.

Starlette's Request._get_form() tries to import parse_options_header from python_multipart.multipart and falls back to multipart.multipart. When neither is available, it asserts parse_options_header is not None and fails.

Fix

Installed python-multipart==0.0.32 into the venv. The requirement was already correct in backend/requirements.txt; the Dockerfile already installs from requirements.txt. The fix is ensuring the dependency is present in the execution environment.
