fix: rework labor tree/list toggle — use Livewire wire:click not Alpine

Previous approach wrapped {{ $this->table }} in x-show which caused
Livewire/Alpine conflicts and broken toggling. New approach:
- viewMode is a Livewire #[Url] property (persisted in URL as ?view=)
- wire:click="setViewMode('list/tree')" triggers a clean Livewire render
- Only one view is rendered at a time (@if, not x-show)
- Tree: Alpine manages per-category open/close state client-side via
  indexed array; Open/Close all buttons use setAll() helper
- Visual overhaul: tighter cards, chevron arrows, proper hover states
