[Feature] General Comment system for wfr entiries

[raylrui]

Context

Currently, comments are only implemented for WorkflowRun entities. We need a more flexible commenting system that allows users to add comments to any entity within the workflow manager (e.g., AnalysisRuns, States, etc.).

Current Limitations

• Comments are tightly coupled to WorkflowRun
• Code duplication would be needed to add comments to other entities
• Limited flexibility for future entity types

Proposed Solution

Create a generic comments system that can be attached to any entity in the system using a Generic Foreign Key relationship.
