similaritySearch throwing Exception due to schema name

Bug description
When doing a similaritySearch using the VectorStore on a database where the schema name contains a - i run into an exception.

PreparedStatementCallback; bad SQL grammar [SELECT *, embedding <=> ? AS distance FROM demo-1998.vector_store WHERE embedding <=> ? < ?  AND metadata::jsonb @@ '($.entityType == "PROCESS" ...)'::jsonpath  ORDER BY distance LIMIT ? ]

I'm pretty sure that it is related to the schema name here. A possible fix could be wrapping the schema name in " on SpringAI side.

Environment
Dependencies using Spring Boot 3.5.4 and Java 20

implementation("org.springframework.ai:spring-ai-starter-mcp-server-webmvc")
implementation("org.springframework.ai:spring-ai-starter-model-azure-openai")
implementation("org.springframework.ai:spring-ai-starter-vector-store-pgvector")

Steps to reproduce

• Do a similaritySearch call on a database schema which has a - in its name

Expected behavior
No exceptions are thrown

Minimal Complete Reproducible example

Start at the VectorStore similaritySearch path that produces the PostgreSQL SQL shown in the exception, and trace how the schema name enters that query. Reproduce with a schema containing a hyphen, then verify that the query completes without an exception and that ordinary schema names still work.
