Add unit tests for 8 more JDBC query DAOs (inline SQL)

[currenjin]

What's this PR about?

Adds unit tests for 8 JDBC query DAOs that use inline SQL or private `buildSQL` methods, requiring Mockito SQL capture.

With the previous rounds (#13800, #13802, #13808), DAO test coverage goes from 18/39 (46%) to 26/39 (67%).

Tests

DAO	Approach	Tests
JDBCMetricsQueryDAO	protected `buildMetricsValueSql()` + Mockito capture	select with aggregation op, TABLE_COLUMN + TIME_BUCKET range + limit
JDBCServiceLabelQueryDAO	Mockito capture	TABLE_COLUMN + SERVICE_ID filter, LABEL column in select
JDBCSpanAttachedEventQueryDAO	Mockito capture	ZK/SW methods: trace ID IN clause, order by start_time asc
JDBCProfileTaskLogQueryDAO	protected `buildSQL()`	TABLE_COLUMN + INDEX_NAME param, ORDER BY OPERATION_TIME DESC
JDBCPprofTaskLogQueryDAO	Mockito capture	TABLE_COLUMN + TASK_ID filter, ORDER BY OPERATION_TIME desc, blank taskId returns empty
JDBCContinuousProfilingPolicyDAO	Mockito capture	TABLE_COLUMN + SERVICE_ID IN clause, single vs multiple placeholders
JDBCAsyncProfilerTaskLogQueryDAO	Mockito capture	TABLE_COLUMN + TASK_ID filter, ORDER BY OPERATION_TIME desc
JDBCAsyncProfilerTaskQueryDAO	Mockito capture	conditional SERVICE_ID/LIMIT, ORDER BY CREATE_TIME DESC, getById with TASK_ID + LIMIT 1

GenAI e2e seems to have some issues.

The OTLP Virtual GenAI and Zipkin Virtual GenAI failures are pre-existing on the master branch (run 24206557119) and are unrelated to this PR. This PR only adds unit tests in the JDBC storage plugin and does not touch any GenAI or OTLP code.
