Merge https://github.com/google/adk-python/pull/2791Fixes#2789
## Summary
Forward `state_delta` from the FastAPI `/run` request to `Runner.run_async(...)`, aligning behavior with the documented
API and the `/run_sse` endpoint.
## Why
The documentation for `/run` explicitly includes:
> `state_delta` (object, optional): A delta of the state to apply before the run.
However, the non‑SSE `/run` handler did not pass this value through, so `Runner.run_async` always received `None`. The
`/run_sse` path already forwarded it correctly.
## Changes
- `src/google/adk/cli/adk_web_server.py`
- Add `state_delta=req.state_delta` to the "/run" handler’s `runner.run_async(...)` call.
- `tests/unittests/cli/test_fast_api.py`
- Add `test_agent_run_passes_state_delta` to test the fix.

This endpoint could be used by ADK Web to dynamically know:
- What are the available eval metrics in an App
- A description of those metrics
- A value range supported by those metrics
We also update the metric registry to make it mandatory to supply these details. The goal is to improve usability and interpretability of the eval metrics.

We update both adk web run eval endpoint and adk eval cli to use the LocalService. The old method is marked as deprecated and will be removed in later PRs.
