feat(models): add Claude Fable 5.1 across Anthropic, Bedrock, Vertex AI, and Azure AI

Browse source 
Adds claude-fable-5-1 cost map entries on the Anthropic API, Bedrock converse
(base, global, and us/eu geo inference profiles at the 10% regional premium),
Vertex AI, and Azure AI. Specs match Fable 5 (1M context, 128K output, $10/$50
per MTok, adaptive thinking always on, xhigh and max effort), except cache reads
land at $0.25 per MTok, a quarter of Fable 5's price and 0.025x base input
instead of the usual 0.1x.

Registers anthropic.claude-fable-5-1 in BEDROCK_CONVERSE_MODELS, lists the model
in the setup wizard, and extends the reasoning effort e2e grid. The partner cells
carry fail_reason markers until access on the CI accounts is confirmed.

Partner entries deliberately carry no deprecation_date: Anthropic publishes
retirement no sooner than 2027-09-01 for the first-party model, and the Foundry
and Vertex dates are not published yet.
