Centraliza configuração de access rules no módulo pai

- Adiciona rota, menu e abas unificados em ldap_groups_sync
- Cria LdapGroupsSyncController (overview dos submódulos)
- Cria UnifiedAccessRulesForm: tabela combinada de regras de todos os
  submódulos habilitados, com único botão "Add Rule"
- Cria GlobalAccessRuleForm: estende AccessRuleFormBase com parâmetro
  {group_type} na rota; exibe select "Group Type" com AJAX rebuild ao
  criar novas regras (desabilitado ao editar)
- Remove rotas access_rules e access_rule_form dos submódulos
- Remove entradas de menu dos submódulos (módulo pai fornece a entrada)
- Atualiza abas dos submódulos para base_route: ldap_groups_sync.config
