refactor(repo): migrate to new object database API

* Replace legacy object store interfaces with new `odb` API
* Update function signatures to include referent param for callbacks
* Use improved object lookup and read methods for consistency
* Simplify file path handling with repository-scoped utilities

Modernizes repository object access for better maintainability and future
compatibility. No functional regressions expected.
