Enforce compiled inpoly kernel in CI tox runs

Add a tox gate to fail when the compiled point_in_polygon kernel is unavailable if OCEANMESH_REQUIRE_INPOLY_ACCEL=1 is set (prints interpreter + compiled status first).
Set OCEANMESH_REQUIRE_INPOLY_ACCEL=1 and OCEANMESH_INPOLY_ACCEL_DEBUG=1 for the Ubuntu tox_tests matrix job so CI won’t silently fall back to the slow Python implementation.
