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 ID while Bedrock equivalents remain

When callers use claude-mythos-5-1 with Bedrock credentials, this blacklist entry permanently removes the canonical catalog record whose fallback_models previously connected it to anthropic.claude-mythos-5-1 and global.anthropic.claude-mythos-5-1. Both provider-specific records and their Bedrock endpoint mappings remain in the catalog, and the audit only established that the Anthropic endpoint returned not-found, so getModelEndpointTypes("claude-mythos-5-1") now returns no endpoints and those existing Bedrock-backed requests become an unknown model. Narrow the canonical record away from Anthropic while retaining its Bedrock fallback relationship instead of excluding the ID entirely.
