Replace per-request `httpx.AsyncClient` with `get_async_httpx_client`
to avoid the +500ms latency penalty from creating new clients per
request. Updates tests to mock the cached client factory.

Fix genuine regression in responses_api_bridge_check where the second
call assigned to `model_info` instead of `responses_api_model_info`,
preventing gpt-5.4 + tools + reasoning_effort from routing to the
Responses API bridge.
Also update outdated tests:
- Vantage tests: match "csv" file key and use supported column names
- Anthropic caching test: add "type": "custom" to expected tool payload
- Claude Agent SDK test: remove non-deterministic LLM content assertion

- DELETE /vantage/delete now removes the in-memory VantageLogger from
litellm.callbacks via remove_callbacks_by_type, preventing the
scheduler from continuing to fire exports with stale credentials
- Add test_should_cast_decimal_columns_to_float covering the
Decimal→Float64 cast in FocusCsvSerializer

- Use timedelta(hours=1) instead of replace(hour=hour+1) in _window()
to avoid ValueError when hour=23
- Add test_should_batch_by_row_count covering the >10K rows batching
path (previously only the 2 MB size-limit path was tested)

Adds a pluggable Vantage destination to the existing FOCUS export pipeline,
enabling LiteLLM to export spend data in FOCUS format directly to Vantage's
cost-import API. Supports automatic hourly exports via scheduled background job,
with admin API endpoints for manual control and configuration. Includes CSV
serializer, batching for 10K row / 2MB API limits, and enriched Tags JSON with
team/user/key metadata for Vantage Token Allocation feature.
- Add CSV serializer (FocusCsvSerializer) for FOCUS data
- Add Vantage API destination with automatic batching
- Add VantageLogger that wraps FocusLogger with Vantage defaults
- Add proxy endpoints: /vantage/{init,settings,export,dry-run,delete}
- Register "vantage" callback in logger registry and literal type
- Wire up background job in proxy_server.py startup
- Populate Tags column with JSON metadata (team_id, user_id, user_email, etc.)
- Add 14 unit tests covering serializer, destination, and factory
All tests pass (23 focus tests total, no regressions).
