[ENH]: ListCollectionsToGc returns lineage file path, group by fork tree, accept optional tenant for filtering

[codetheweb]

Description of changes

Includes several updates to the ListCollectionsToGc gRPC method:

• returns the lineage file path, if present
• only returns the root collection for fork trees
• accepts an optional tenant parameter for test isolation.

Because ListCollectionsToGc now returns collections that are part of fork trees, I also updated GC to skip collections with a populated lineage_file_path (i.e. the root collection in a fork tree).

Test plan

How are these changes tested?

Added tests covering the fork tree grouping and GC behavior on forked collections.

Documentation Changes

Are all docstrings for user-facing APIs updated if required? Do we need to make documentation changes in the docs section?

Enhanced ListCollectionsToGc for Fork Tree Management

This PR enhances the ListCollectionsToGc gRPC method to return lineage file paths, group collections by fork trees, and add tenant filtering capability. The changes also update the garbage collector to skip collections with lineage files to prevent premature cleanup of fork trees.

Key Changes:
• Modified ListCollectionsToGc to return lineage file path information
• Changed query logic to group by fork trees and only return root collections
• Added tenant parameter for filtering collections during GC
• Updated garbage collector to skip collections with lineage files

Affected Areas:
• gRPC API contracts for garbage collection
• Garbage collector component
• Collection model and database query logic
