update RDK and vision service signatures to NamedImage

[bhaney]

go.mod — bumped go.viam.com/rdk to v0.124.0-rc0.0.20260428155858-62da9535aca4 (transitive bumps via go mod tidy).

waitsensor/waitsensor.go

• Added go.viam.com/rdk/data import (for data.Annotations{} when re-wrapping cropped images).
• Added a getNamedImageFromCamera helper that calls cam.Images() and returns the first *camera.NamedImage.
• The counter.run loop now:
  • Pulls a *camera.NamedImage directly from the camera (replaces camera.DecodeImageFromCamera).
  • In the no-bounding-box branch, passes the *camera.NamedImage straight to cs.detector.Detections.
  • In the bounding-box branch, decodes the NamedImage to image.Image once via namedImg.Image(ctx), runs the existing BoundingBox.Crop logic, then re-wraps each crop with camera.NamedImageFromImage (preserving source name and mime type) before calling
    cs.detector.Detections.
