Pull request overview
Adds an HTTP API surface (types + routing + OpenAPI spec) for a planned full-text search (BM25) capability in the vector-store service.
Changes:
- Registers a new POST endpoint:
/api/v1/indexes/{keyspace}/{index}/bm25(currently returns 501 Not Implemented). - Introduces request/response schemas for BM25 search in the
httpapicrate. - Updates the checked-in OpenAPI spec (
api/openapi.json) to include the new endpoint and schemas.

ScyllaDB needs to support full-text search queries through the vector store service. This adds the client-side BM25 endpoint so ScyllaDB can request ranked full-text search results from the vector store, alongside the existing ANN (approximate nearest neighbor) endpoint. Tests are added mirroring the ann() test suite. The test infrastructure is extended with a mock server mode and a lightweight schema builder helper to avoid spinning up a full CQL environment where it is not needed. Fixes SCYLLADB-1511 Ref scylladb/vector-store#471

Add the /api/v1/indexes/{keyspace}/{index}/bm25 POST endpoint that
will perform BM25 full-text search. Currently returns 501 Not
Implemented.
