chore(data-warehouse): Condensed joins UI

[Gilbert09]

Problem

• We had tabs in the data warehouse scene, one for the tables and another for managing joins
• We want to move the warehouse stuff into data pipelines 3000, and so getting rid of the joins tab would make the transition much easier

Changes

• Condensed the joins UI and logic into the tables views
• Can edit and delete joins from the table (from the individual columns)
  • Works on both posthog and warehouse tables
• Removed the Joins tab and relevant components

Does this work well for both Cloud and self-hosted?
