Fix: team members no se persistían ni cargaban al inicio

- Bug: App.vue llama fetchProjects() antes de que ProjectListView
  monte, el watch de projects.length nunca se disparaba
- Fix: watch con immediate:true + dependencia dual (projects +
  users), guard teamInitialized para ejecutar una sola vez
- Garantiza que loadAllTeams corra cuando AMBOS datos estén listos
