refactor(livewire): organizar componentes y vistas por dominio en subnamespaces

- app/Livewire: 34 componentes agrupados en Issues/, Projects/, Phases/,
  Companies/, Users/, Admin/, Inspections/, Layers/, Media/, Common/
  (Client/, Reports/, Forms/, Actions/ ya estaban). Namespaces actualizados.
- resources/views/livewire: vistas sueltas movidas a subcarpetas espejo
  (companies/, users/, phases/, roles/, inspections/, media/, common/);
  render() actualizado.
- Referencias actualizadas sin romper nada: rutas (FQN, nombres de ruta intactos),
  tags <livewire:...>/@livewire() a alias con punto, y use de los tests.
- No tocado: Volt de Breeze (auth/profile/navigation), y el portal cliente
  (user-nav/client-projects) que ya tenía referencias inconsistentes.

Verificado: 69 rutas OK, vistas compilan, suite 69 passing (solo 2 pre-existentes
sqlite). autoload regenerado con --ignore-platform-reqs (PHP 8.2).
