litellm_fix(tests): fix budget tests and Claude Agent SDK tests

1. Remove bedrock-nova-premier from Claude Agent SDK tests
   - Nova Premier is NOT a Claude model - it's Amazon's model
   - The Claude Agent SDK expects Claude-specific response formats
   - This was causing test_claude_agent_sdk_streaming[bedrock-nova-premier-AWS Nova Premier] to fail

2. Add pricing to fake-openai-endpoint model in both config files
   - proxy_server_config.yaml (used by test_users_in_team_budget)
   - otel_test_config.yaml (used by test_chat_completion_low_budget)
   - Without pricing, spend is always 0 and budget is never exceeded
   - Added input_cost_per_token: 0.0001 and output_cost_per_token: 0.0002

Fixes:
- test_claude_agent_sdk_streaming[bedrock-nova-premier-AWS Nova Premier]
- test_chat_completion_low_budget
- test_users_in_team_budget
