feat: adicionar painel admin e fortalecer controle de acesso

- adiciona workspace front_admin com dashboard, usuarios, scrapers,
  observabilidade, auditoria e permissoes
- integra o front_admin ao monorepo, scripts npm, Docker Compose
  e build multi-stage
- cria endpoints administrativos para usuarios, observabilidade
  e regras de permissoes
- adiciona persistencia de regras RBAC e atualiza matriz de permissoes
- isola keywords por usuario e propaga userId nos eventos de sincronizacao
- adiciona rate limit nas rotas de login e cadastro
- atualiza migrations, testes, env examples e configuracoes de build/teste
- protege builds Docker contra inclusao de envs e artefatos locais
