Add customizable tags parameter to health check methods

Implements issue #679: Allow users to customize tags for health checks via optional parameter.

- Added optional `tags` parameter to AkkaPersistenceJournalBuilder.WithHealthCheck()
- Added optional `tags` parameter to AkkaPersistenceSnapshotBuilder.WithHealthCheck()
- When tags parameter is null, defaults to ["akka", "persistence", "journal"] or ["akka", "persistence", "snapshot-store"]
- Consolidates previous overloads into single method with all optional parameters to avoid ambiguity
- All 18 health check tests pass
