feat(configmanager): add LdapFormViewModel

Implement LdapFormViewModel for editing LDAP configuration section with
properties for ServerUrlsText, GroupDn, SearchBase, ConnectionTimeoutSeconds,
UseFakeAuth, and AdminBypassUsersText. Array properties use newline-separated
text with StringSplitOptions.RemoveEmptyEntries | TrimEntries for splitting.
