Add ImageCatalog and InstalledPackages modules for package management

- Introduced `ImageCatalog` for handling catalog-related operations, including initialization, building from publishers, querying, and manifest management.
- Added `InstalledPackages` for managing installed package operations, such as adding, removing, querying, and retrieving manifests.
- Defined database schemas and error types to support both modules.
- Refactored table handling, ensuring consistent transaction scoping with `redb`.
