bindDn and bindPassword are now optional on LdapConfig (nullable
migration) and throughout the DTOs/service/client -- an admin can
leave both blank to connect to directories that permit anonymous
read access. LdapService.bind() falls back to an RFC 4513 anonymous
bind (empty DN + empty password) whenever either field is missing,
shared across testConnection, listGroups, and syncUsersForTenant.
Frontend: removed the required attribute from Bind-DN/Bind-Passwort,
added a placeholder hint ("leer = anonymous bind"), and the
"Verbindung testen" button now only needs a Server-URL to enable
(not bindDn+bindPassword). Config responses now return bindPassword
as null (not a misleading "********") when no password is set.
Verified locally: submitted only a Server-URL with both bind fields
empty and confirmed the request reached the anonymous-bind code path
(DNS failure for the unreachable test host, not a validation error).
