🎨 Async/Await migration on bucketGet and objectGetLegalHold

[DarkIsDude]

Issue: CLDSRV-823

Description

Motivation and context

Opening a first PR to migrate from callback to async/await syntax. A TAD is opened.

https://scality.atlassian.net/wiki/spaces/OS/pages/3523346468/2025-10-30+-+Async+Await+migration

This is a first PR to start the migration. As mention in the TAD, the idea is to migrate to async/await when working on a specific part of our component. Maybe a common goal of one PR per squad per sprint is a good idea.

All idea or remarks are welcome 🙏
