Features:
- SpaceLayoutManager: full CRUD for facility layouts (grid/lanes/zones/custom)
  with visual segment preview and toggle availability
- SpaceAssignmentWizard: 5-step wizard for assigning groups to facility segments
  Step 1: Search and select training group
  Step 2: Choose which schedule slot to assign
  Step 3: Pick the facility (if not already linked)
  Step 4: Visual grid/lane/zone selector with real-time collision detection
  Step 5: Success confirmation
- Visual grid renders as clickable cells showing available/selected/occupied/disabled states
- Real-time collision checking against existing confirmed reservations
- Saves space_reservation_template on TrainingSchedule for auto-reservation on session creation
- Fix: ReservationService.autoReserveForSession() now uses correct field names
  (space_reservation_template instead of segments, segment_ids instead of segments key)
- Added "التخطيط" action link in facility list table
- Added "تعيين المساحات" to sidebar navigation

Audited all varchar-limited columns vs code that generates values for them:

- BranchForm: validation was max:20 but column is varchar(10) — fixed
- ActivityService: Str::slug output now capped at 90 chars (column is 100)
- TrainingProgramService: same slug truncation fix
- SetupWizard: slug generation for activities/programs also truncated
- Logout: removed navigate:true (app→guest layout cross breaks)

Affected columns and their limits:
  branches.code = varchar(10) ✓ fixed
  training_groups.code = varchar(10) ✓ already validated
  activities.slug = varchar(100) ✓ now truncated
  training_programs.slug = varchar(100) ✓ now truncated

Str::slug on Arabic names can produce codes longer than 10 chars.
Added Str::limit(..., 10, '') to truncate. Also removed navigate:true
from redirects to avoid Livewire SPA issues between layouts.

Replaced x-data/x-show/x-transition with @if($currentStep === N)/@endif.
Livewire re-renders the component on each step change, so only the
active step's HTML is sent to the browser. No JS needed, no entangle,
no Alpine timing issues.

1. app.js was importing and starting Alpine manually, but Livewire 3/4
   already bundles Alpine. Two instances meant $wire magic was unavailable.
   Now app.js just registers the focus plugin via Livewire's alpine:init hook.

2. Wizard x-data used @entangle which compiled to the old
   window.Livewire.find(id).entangle() syntax. Replaced with $wire getters
   which is the canonical Livewire 3+ approach.

Livewire components use $this->authorize() which goes through Laravel's
Gate system. Without a Gate callback, super_admin gets 403 because no
policies exist. Gate::before delegates all ability checks to our
PermissionService (which returns true for is_super_admin).

Sidebar: route names in navigation array didn't match actual registered
routes (e.g. 'participants.index' vs 'participants.list'). Remapped all
entries to match the real route names from route:list.

Login: replaced `redirect(navigate: true)` with `redirectIntended()` —
Livewire SPA navigation between different layouts (guest→app) fails
silently, requiring a manual page refresh.

The @php block starting at line 1 was never closed before another @php
was opened at line 99, causing "unexpected variable $permissionService".

1. Remove double <aside> wrapper (app.blade.php was wrapping sidebar in
   its own aside, conflicting with sidebar's own fixed positioning)
2. Replace auth()->user()->can() with PermissionService->can() which
   properly handles is_super_admin bypass

Laravel 13's Symfony dependencies require PHP >= 8.4.1. The container was
crash-looping because the entrypoint hit Composer's platform check against
the 8.3 runtime.
