Move duplicated Cargo dependencies to the root workspace manifest, switch member crates to workspace dependencies, and align non-conflicting shared feature sets at the workspace level.
Upgrade a number of shared dependencies while consolidating versions across the workspace. This also consolidates the ldap3 dependency in response to GHSA-qcxq-75wr-5cm8: https://github.com/kanidm/ldap3/security/advisories/GHSA-qcxq-75wr-5cm8
Update frontend and migration code for dependency upgrades and clean up manifest structure.
