What does this change?

Implements the More Like This and semantic search features using GCP APIs rather than AWS Bedrock.

Uses Gemini Embedding 2 as the model.

Scales uploaded images using ImageOperations before submitting them to the prediction API.
Every image is scaled rather than relying on the original or optimised image.

Does not need a separate Lambda.

How should a reviewer test this change?
