test: enumerate PyArrow primitive type mappings

[emecii]

Closes #3714

Rationale for this change

PyArrow-to-Iceberg conversion tests cover supported primitive types individually, but the expected PyArrow and Iceberg-spec Parquet physical mappings are not collected in one contract. This table-driven test covers the supported primitive mappings, including UUID, fixed binary, timestamp variants, and all three decimal physical-width bands.

Are these changes tested?

• make test PYTEST_ARGS='-q' — 4,033 passed, 3 skipped, 1,571 integration-marked tests deselected by the project target.
• Focused visitor suite — 77 passed.
• Ruff, Ruff format, mypy, pydocstyle, codespell, and lockfile hooks passed.

make check-license could not run locally because no Java runtime is installed. This PR changes one existing test file and adds no source files.

Are there any user-facing changes?

No runtime behavior changes. The expanded regression contract protects type-conversion compatibility.

Hi @emecii,
I'm not sure if this is in scope of what you are trying to do. But see this comment from @sungwy

I havn't had to time to back to my stale PR, but maybe its something worth looking into as part of this PR?
