Fix Bedrock Claude Sonnet 4.6 model ID, cc #11509

[PeterDaveHello]

This PR fixes the Bedrock model ID for Claude Sonnet 4.6.

• Replaced the incorrect Bedrock model ID:
  • from anthropic.claude-sonnet-4-6-20260114-v1:0
  • to anthropic.claude-sonnet-4-6
• Updated Bedrock 1M/global inference model ID lists to use the corrected ID.
• Updated Bedrock tests to use the corrected Sonnet 4.6 ID.

Scope is intentionally minimal and focused on the incorrect Bedrock identifier.

Test Procedure

1. Run Bedrock provider tests:
   • pnpm --filter roo-cline exec vitest run api/providers/__tests__/bedrock.spec.ts
2. Confirm the Sonnet 4.6 ID references are corrected in:
   • packages/types/src/providers/bedrock.ts
   • src/api/providers/__tests__/bedrock.spec.ts
