fix(providers): minimax-m3 collapses manual thinking.type:enabled to adaptive (#12132)

The minimax-m3 modelSpecs entry never received adaptiveThinkingOnly:
true (issue #9155 proposed the one-line change but no PR landed it).
Both normalizeClaudeAdaptiveThinking() and the explicit
thinking.type:"enabled" branch in openai-to-claude.ts gate purely on
isAdaptiveThinkingOnly(model), so a manual thinking.type:"enabled"
request routed to MiniMax M3 (via either the minimax or minimax-cn
provider, since both alias to the same spec entry) was forwarded
unchanged and rejected upstream with 400 (2013).

Adding adaptiveThinkingOnly: true to the minimax-m3 spec entry closes
the gap for every call path (direct, combo, cache-rebuild).
