chore: Remove duplicate JOOQ generator and libraries

[aglinxinyuan]

Since the JOOQ code generator logic was merged into the sbt compiler in PR #3746, we no longer need a separate JOOQ generator class. This PR removes the redundant JOOQ generator along with its related libraries.

If you look at the file changes, the files removed in this PR are symmetrical to those added in PR #3746. We chose not to remove everything in the same PR to ensure the new generator worked as expected before deprecating the old one, and to keep each PR minimal and focused.

Waiting for @seongjinyoon to add an sbt shortcut to run JOOQ generator in case developers want to run it manually. It's not urgent. Will merge after fixing issue #3917
