P2 Badge Allow reasoning_effort for dotted Claude 4.6 aliases

This adds dotted alias handling to _map_reasoning_effort, but the normal completion flow validates params against get_supported_openai_params() before this mapping runs, and that list only includes reasoning_effort when supports_reasoning(model) is true. Because the Anthropic model map does not include claude-opus-4.6* / claude-sonnet-4.6* keys, those aliases still fail support detection and reasoning_effort is rejected as unsupported in utils._check_valid_arg, so the new dotted-alias reasoning mapping is unreachable in production requests.
