test(runtimes): pin combined provider+dotted+dated Claude normalization (#2657)

Adds a regression test for `anthropic/claude-opus-4.7-20251001` that
exercises all three resolvePricing tolerances at once (provider strip,
Claude dot→dash, date trim). Each step was already covered pairwise;
this nails down their composition so a future change to candidate
ordering can't silently drop a step.

Follow-up to #2654 (MUL-2243); raised in second review.
