{Documentation} Client SDK - Add multi-device callouts to single-device pages

Summary:
Explanation:

Adds three lightweight `:::tip` callouts on the single-device pages so readers discover the multi-device guide and the `device_id` callback pattern. Three files:

- `client-sdk/recording.mdx` — "Multiple devices?" tip after the existing auth caution, pointing at the multi-device guide.
- `client-sdk/streaming.mdx` — same tip as above, scoped to streaming.
- `client-sdk/python-sdk/streaming-example.mdx` — "Multi-device callbacks" tip at the top of "Code Walkthrough", documenting the optional `device_id` callback parameter and pointing at the multi-device streaming example.

Reproducibility:

Render `client-sdk/` locally and verify each tip renders below the existing auth caution on `recording.mdx` / `streaming.mdx`, and at the top of "Code Walkthrough" on `streaming-example.mdx`.

 ## Available Recording Profiles
 
 Before starting a recording, you need to select a recording profile that defines the sensor configuration, data rates, resolutions, and encoding formats. Project Aria Gen2 offers several pre-defined profiles:
