test(spog): skip SPOG functional tests on pre-SPOG deps

Add a session-scoped autouse fixture that calls pytest.skip when either
the installed databricks-sdk or databricks-sql-connector pre-dates SPOG
support. The fixture short-circuits before any setup, so min-deps runs
(sdk 0.68.0 + connector 4.1.2) no longer attempt to open SPOG-decorated
connections that the floor stack can't honor.

Verified in the min-deps hatch env: all 3 SPOG tests skipped in 0.01s.
