[shin-bot-litellm]

Summary

Fixes failing mapped tests.

---

⚠️ Regression Analysis

1. Azure AI Cost Calculator Test

Test: test_additional_costs_in_cost_breakdown
Status: New test with bug (not a regression)
Introduced in: PR #20091 (5345a76) - "[Feat] v2 - Logs view with side panel"
Issue: Test imports non-existent LitellmLoggingObject class
Fix: Use Logging class with required parameters

2. Bedrock Tool Search Header Test

Test: test_advanced_tool_use_header_filtered_for_non_opus_4_5
Status: REGRESSION
Breaking commit: 7d5439a - PR #19871 "fix(bedrock): support tool search header translation for Sonnet 4.5"
Date: 2026-01-27
Why it broke: Test assumed only Opus 4.5 supports tool-search on Bedrock. PR #19871 added Sonnet 4.5 support, invalidating the test assumption.
Risk: ⚠️ LLM translation test - higher risk area
Fix: Change test model from Sonnet 4.5 to Claude 3.5 Sonnet (which genuinely does NOT support tool-search)
