support plain DataSource

[devhawk]

DBOS uses HikariDataSource if a data source is not provided. This PR updated sysdb + dbos config to support base DataSource (i.e. non Hikari data sources)

Also added DBOS.registerQueues to register more than one queue at a time

Pull request overview

This PR adds support for plain DataSource interfaces instead of requiring HikariDataSource throughout the codebase. The change enables using any JDBC DataSource implementation, such as PGSimpleDataSource, while maintaining backward compatibility with Hikari-specific features when a HikariDataSource is provided.

Changes:

• Updated all DAO classes and SystemDatabase to use the generic DataSource interface instead of HikariDataSource
• Removed redundant isClosed() checks that are specific to HikariDataSource
• Added runtime type checks to conditionally access Hikari-specific features like pool management
• Updated DBOSConfig to accept any DataSource implementation
• Added test coverage for using PGSimpleDataSource alongside existing HikariDataSource tests

Not really. I mean if you provide a non Hikari data source, then you won't get Hikari data source logs, but otherwise doesn't change anything related to logging
