pytc.test.test_panel_blk_override

Focused tests for the PYTC_PANEL_BLK / PYTC_GPU_MAX_MEMORY_MB env-var panel/block-size overrides and the _FIXED_RBS_CACHE cache-key invariants.

Covers: - _panel_blk_overrides() parsing (default None, set values, bad values). - Cache-key correctness: a same-process env change invalidates a stale cached

rank_block_size, and repeated same-env calls hit the cache without recompute.
