chore: remove deprecated models from the catalog

[github-actions]

Model deprecation audit

Each model below returned a definitive not-found / deprecated response from its provider (a single 404 / not-found is treated as authoritative). Account/region-scoped providers (bedrock, vertex, databricks) are surfaced for manual review, not auto-removed.

{
  "deprecations": [
    {
      "model": "claude-opus-4-1",
      "provider": "anthropic",
      "reason": "absent from list + probe not-found",
      "status": 404,
      "detail": "{\"type\":\"error\",\"error\":{\"type\":\"not_found_error\",\"message\":\"model: claude-opus-4-1\"},\"request_id\":\"req_011Cdm5bTrnkJuaDYqVYy5g1\"}"
    },
