feat(difs): Add capability to read difs from Objectstore

[lcian]

This is the first step in the migration of Debug Files to Objectstore.
It makes the File FK on ProjectDebugFile nullable, and introduces new columns for Objectstore-backed DIFs.

I would probably split the PR to lower the risk: one for the migration and one for the new business logic.

I would probably split the PR to lower the risk: one for the migration and one for the new business logic.

The business logic does essentially nothing until we start writing in #117294.
But I'll take the suggestion and try splitting it, that might make the PR a little easier to review.

Superseded by a split stack: #117500 (migration) -> #117501 (read logic) -> #117294 (write logic)
