Daniel Han 9d2aa80953 Studio: longest-prefix pricing match + accept chat-style usage keys
Two P1 / High follow-ups from PR 5690 review feedback:

1. Pricing prefix lookup returned the first key it iterated, so
   dated snapshots like ``gpt-5.4-mini-2026-04-23`` collided with
   the shorter ``gpt-5.4`` entry and overbilled by 3x+. Sort the
   table keys longest-first so the most specific entry wins.

2. ``calculate_cost`` only read ``input_tokens`` / ``output_tokens``,
   but Studio's OpenAI-Chat-style usage envelope re-emits
   ``prompt_tokens`` / ``completion_tokens`` (the OpenAI Chat
   Completions vocabulary). Callers handing in the chat-style
   shape silently got a zeroed bill. Accept either pair so the
   calculator works against both raw upstream usage and the
   Studio-translated envelope.

Tests (4 new in test_pricing.py): dated mini/pro snapshots inherit
the right rate; chat-style usage keys price correctly; raw key wins
when both shapes are present.
