feat(llm_flows): support async before/after tool callbacks

Previously, callbacks were treated as purely synchronous,
so passing an async coroutine caused “was never awaited”
errors and Pydantic serialization failures.

Now we detect awaitable return values from
before_tool_callback and after_tool_callback,
and `await` them if necessary.

Fixes: #380

Refactor function callback handling and update type signatures

- Simplify variable names in `functions.py`: always use `function_response` and `altered_function_response`
- Update LlmAgent callback type aliases to support async:
  - Import `Awaitable`
  - Change `BeforeToolCallback` and `AfterToolCallback` signatures to return `Awaitable[Optional[dict]]`
- Ensure `after_tool_callback` uses `await` when necessary
