test(minimax): assert M3 stale-cache guard contract, not a brittle 1M literal (#37220)

Browse Source 
test_stale_m3_cache_dropped_and_reresolves_to_1m hardcoded
assert ctx == 1_000_000. The test re-resolves M3 through the live models.dev
registry (the seeded stale entry is dropped, so nothing short-circuits the
lookup), and models.dev now reports MiniMax-M3 at 512,000 — a change-detector
failure unrelated to any code change.

The guard's actual contract is: a stale <=204,800 catch-all value for an M3
slug must be DROPPED and re-resolved to M3's real (large) context. Both
sources satisfy that (hardcoded catalog 1,000,000; models.dev 512,000), so
assert the invariant (ctx > 204,800, stale value gone) instead of a literal
that external data can move. Renamed accordingly.

47/47 in test_minimax_provider.py pass.
