fix(ai): recognise Claude 5 and Fable models as vision-capable

The Anthropic vision check listed the Claude 3 and 4 families by prefix,
so a key pinned to claude-sonnet-5, claude-opus-5 or a Fable model was
told the provider cannot read images, and lab and document OCR refused
the upload even though the model handles image and PDF blocks.

Replace the per-release prefix list with a rule: any claude-<tier>-<major>
slug from the 4 family upward, plus every claude-fable-* model, counts as
vision-capable. Claude 3 handling is unchanged. The Settings preset list
gains claude-sonnet-5 and claude-opus-5 alongside the existing entries.
