feat(api): add model filter to embeddings API and fix history navigation

Add model name filter to embeddings API (similar to completions API)
and fix the history button in models registry to navigate to the
correct page based on model type.

Changes:
- Add `model` parameter to `listEmbeddings` function with LIKE query
- Add `model` query parameter to GET /admin/embeddings endpoint
- Add `model` to frontend embeddings route search schema
- Update history button to navigate to /embeddings for embedding models
  and /requests for chat models
