Pull request overview

This PR aligns the versioned-object indexes introduced in #1341 with the repository’s established bytewise sorting/search behavior by applying COLLATE "C" to storage.objects.name in those indexes, ensuring consistent index semantics with existing name-based comparisons.

Changes:

• Add COLLATE "C" to name in the (bucket_id, name, version) unique index.
• Add COLLATE "C" to name in the “current version” unique index (archived_at IS NULL).
• Add COLLATE "C" to name in the “null version” unique index (NOT is_versioned).
