fix(labs): allow Claude 3 vision models for OCR

The vision allowlist matched only the 3.5/3.7/4 families, so a
self-hoster pinned to claude-3-opus / claude-3-sonnet / claude-3-haiku
was wrongly blocked from lab OCR though those models read images. Add
the bare claude-3-{opus,sonnet,haiku} prefixes.
