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.

Preserve the canonical alias while Bedrock variants remain

When a caller selects claude-mythos-5-1 with Bedrock credentials, the removed catalog entry's fallback_models previously linked it to the still-present anthropic.claude-mythos-5-1 and global.anthropic.claude-mythos-5-1 Bedrock entries, allowing getModelEndpointTypes() to include bedrock. Adding the canonical ID to this global exclusion list based only on the Anthropic 404 removes that fallback graph, so the canonical ID now resolves to no endpoint types even though its Bedrock variants were explicitly left unaudited and remain cataloged; remove only the dead Anthropic route while retaining the canonical-to-Bedrock linkage.
