fix(wake): resolve probe model dynamically from /v1/models by 'haiku' match

The wake probe was hardcoded to claude-3-5-haiku-20241022, which the
endpoint no longer serves (HTTP 404), exhausting the retry loop. Now the
probe fetches the live model list via fetchAnthropicModels (falling back
to ANTHROPIC_MODELS_FALLBACK if empty) and selects the current Haiku via
a new pure selectHaikuModel() helper (first case-insensitive 'haiku'
substring match; newest-first ordering). No-match surfaces a clear
per-account error instead of crashing.
