LDAP: Show non-matched groups returned from LDAP (#19208)

* LDAP: Show all LDAP groups

* Use the returned LDAP groups as the reference when debugging LDAP

We need to use the LDAP groups returned as the main reference for
assuming what we were able to match and what wasn't. Before, we were
using the configured groups in LDAP TOML configuration file.

* s/User name/Username

* Add a title to for the LDAP mapping results

* LDAP: UI Updates to debug view

* LDAP: Make it explicit when we weren't able to match teams
