fix(db): remove duplicate unique constraints from drizzle schema

Remove auto-generated duplicate constraint names (uknlcwyn..., uk6cjmvj...)
that exist in local PostgreSQL but not in CI's fresh H2 database.
These are duplicates of the named constraints (uq_discussion_repo_number,
uq_discussion_category_repo_slug).
