fix(provider/anthropic): normalize model ID dots to dashes before API call

Browse source 
The Anthropic API expects hyphens in model IDs (e.g. claude-sonnet-4-6),
but config files use dots (claude-sonnet-4.6). The dot-to-dash
normalization only existed in the SDK-based provider, so API-key and
anthropic-messages paths sent the dotted name and got a 404.
