feat: add WHERE clause test coverage for MongoDB and Azure SQL connectors

[Copilot]

TableConfiguration.whereClause was already wired through the pipeline (JobService → fetchData → all four connectors), but MongoDBConnector and AzureSQLConnector had no test coverage for their fetchData WHERE clause and limit behaviour.

Changes

• MongoDBConnectorTest — three new fetchData tests verifying the correct BSON filter document is passed to collection.find():

  • no whereClause → find(Document()) (empty filter)
  • whereClause provided → find(Document.parse(whereClause))
  • limit provided → findIterable.limit(n) is called

  Uses RETURNS_DEEP_STUBS to handle the MongoIterable.map(...).toList() chain without boilerplate.

  connector.fetchData("users", whereClause = """{"age": 18}""")
  verify(mockCollection).find(Document.parse("""{"age": 18}"""))

• AzureSQLConnectorTest (new file) — full connector test suite using H2 in MODE=MSSQLServer (supports SELECT TOP n and [bracket] identifiers). Covers testConnection, fetchData with/without WHERE clause and with row limit, writeData, and truncateTable. Passes null credentials so the connector uses the simple DriverManager.getConnection(url) path, avoiding Azure-specific JDBC properties.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• example.com
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java -Dorg.gradle.internal.worker.tmpdir=/home/REDACTED/work/OpenDataMask/OpenDataMask/backend/build/tmp/test/work -Dorg.gradle.native=false -javaagent:/home/REDACTED/work/OpenDataMask/OpenDataMask/backend/build/tmp/.cache/expanded/zip_0bd0851504e6286cb5fc6f37a81e25cc/jacocoagent.jar=destfile=build/jacoco/test.exec,append=true,inclnolocationclasses=false,dumponexit=true,output=file,jmx=false @/home/REDACTED/.gradle/.tmp/gradle-worker-classpath10669771887708325242txt -Xmx512m -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -ea worker.org.gradle.process.internal.worker.GradleWorkerMain 'Gradle Test Executor 2' (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
