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.
Add a modifyTimestamp attribute to LDAP entries for users and groups, and expose pwdChangedTime for users.
These attributes let clients track when an entry (or its password) was last changed.
- modifyTimestamp is a server-maintained attribute that updates on any write to user or group entries, including membership changes (on the group side).
- pwdChangedTime is set when a user’s password is created or changed.
