fix: correct provider MPS rows

[guillaumegay13]

Summary

• correct OpenAI API-key MPS rows against the official Chat Completions schema and live behavior
• correct Anthropic API-key MPS rows, including current dated Claude 4.x IDs and Opus 4.7 adaptive-thinking rules
• correct DeepSeek API-key MPS rows so current DeepSeek models and legacy aliases expose the thinking toggle/effort without invalid sampling combinations

Official docs checked

• OpenAI Chat Completions API: max_completion_tokens, temperature, top_p, and reasoning_effort model constraints
• Anthropic Claude Opus 4.7 docs: adaptive thinking only, no fixed thinking budgets, no non-default sampling params
• Anthropic effort docs/model overview: current Claude 4.x model IDs and effort behavior
• DeepSeek Chat Completion + Thinking Mode docs: thinking.type, reasoning_effort, sampling behavior while thinking is enabled

Live smoke coverage

• OpenAI API-key catalog re-smoked: accessible rows had no parameter-shape failures; chatgpt-4o-latest, o1-mini, and o1-preview returned 404 for this test key, so they are left as a separate coverage/pruning policy question
• Anthropic targeted current rows: Opus 4.7 adaptive/effort rules pass; deprecated sampling and fixed-budget thinking fail as expected and are no longer exposed
• DeepSeek targeted rows: deepseek-chat, deepseek-reasoner, deepseek-v4-flash, and deepseek-v4-pro pass for supported parameter combinations; sampling params are hidden while thinking is enabled
• Post-patch dependency-aware smoke on changed Anthropic/DeepSeek rows: 118 live calls, 0 failures

Notes

• This intentionally does not include the reusable live smoke harness from closed PR fix: harden OpenAI and Anthropic model params #4. That should remain a separate PR.
• This PR removes DeepSeek rows rejected by the live API (deepseek-v3.1, deepseek-v3.2, deepseek-v4) and keeps the accepted aliases (deepseek-chat, deepseek-reasoner).
