feat: RBAC catalog + 2FA UX (P0 blocker from /tmp/service/new/01-TZ)

Implements the RBAC TZ in app/Auth/Permissions.php with a 51-permission
catalog spanning 9 modules (clients/vehicles/work_orders/finance/salaries/
inventory/suppliers/admin/ai_assistant+analytics). All slugs are constants,
not magic strings — refactors against renames stay safe.

== 7 system roles ==
owner / admin / manager / accountant / receptionist / mechanic / viewer
Each gets a curated role-permission matrix per the TZ section 2.4:
- owner + admin: all 51
- manager: 23 (operations + reporting, no destructive finance/users)
- accountant: 17 (full finance/salaries, view-only WOs, no admin)
- receptionist: 13 (front-desk: clients/vehicles/WOs/payment-create)
- mechanic: 4 (own WOs + inventory view + own salary)
- viewer: 6 (read-only everything except finance/salaries)

== Seeder ==
App\Services\RbacSeeder:
- seedPermissions() creates the 51 Permission rows globally (idempotent)
- seedTenantRoles($companyId) sets the team context, creates the 7 Role
  rows scoped to that tenant, and syncPermissions per matrix
- syncUsersToRoles($companyId) maps legacy users.role string column to
  the new Spatie role assignment (parts_manager→manager, master→mechanic,
  marketer→manager, user→viewer)

== Migration ==
2026_06_04_000003 loops over all existing Companies and runs the seeder.
On a fresh prod deploy, every tenant gets the full RBAC catalog wired up
automatically. CompanyProvisioner::provision() also calls the seeder for
new tenants going forward.

== Resource gates ==
canViewAny / canCreate / canDelete on:
- PaymentResource (FINANCE_VIEW_OVERVIEW / FINANCE_CREATE_PAYMENT / FINANCE_DELETE_PAYMENT)
- ExpenseResource (FINANCE_VIEW_OVERVIEW / FINANCE_CREATE_EXPENSE / FINANCE_DELETE_PAYMENT)
- PayrollAdjustmentResource (SALARIES_VIEW_ALL / SALARIES_CALCULATE)
- PayrollRunResource (SALARIES_VIEW_ALL / SALARIES_CALCULATE)
- UserResource (ADMIN_USERS_VIEW / ADMIN_USERS_MANAGE)
- RoleResource (ADMIN_ROLES_MANAGE)

Mechanic sees only own WOs + inventory + own salary. Accountant sees all
finance but not admin. Receptionist sees clients/WOs but not finance
overview. Etc.

== User helpers ==
$user->canDo(Permissions::WORK_ORDERS_CREATE) — admin gets a bypass to
prevent lockouts from misconfigured permission grants.
$user->isOwner() / isAccountant() / isMechanic() — role shortcuts.
$user->hasTwoFactorEnabled() — true when app_authentication_secret is set.

== 2FA ==
Filament 5's native MultiFactorAuthentication (App + Email) is already
enabled in both TenantPanelProvider and CentralPanelProvider — confirmed.
The User model already implements HasAppAuthentication +
HasAppAuthenticationRecovery + HasEmailAuthentication.

This commit adds UX around it:
- UserResource list column: 2FA badge (green ✓ when enabled, amber ⚠ when off)
- UserResource form: "Securitate" section shows enabled/disabled + last_login_at
- New admin action "Resetează 2FA" with confirmation modal — clears
  app_authentication_secret + recovery codes for locked-out users

== Roles management UI ==
New /app/roles RoleResource:
- List: role label + slug + permission count + user count
- Edit: 10 grouped checkbox lists (per module) for fine-grained
  permission assignment + bulk-toggle per group
- System roles (owner/admin/etc.) have slug locked, can't be deleted
- Custom tenant-specific roles can be added on top
- Gated behind ADMIN_ROLES_MANAGE

== UserResource extension ==
- Role select now uses Permissions::roleLabels() (owner/admin/manager/...)
- New "Roluri suplimentare" multi-select for stacking roles on top of
  the primary one (permissions cumulate)
- afterSave syncs the picked roles + ensures primary role is always
  included

== Tests ==
RbacTest covers: 51 permissions seeded, 7 roles per tenant, owner has
all, mechanic has minimal, accountant has finance but not admin,
canDo returns true when role has permission, admin bypass, owner helper,
syncUsersToRoles legacy mapping (parts_manager→manager, master→mechanic,
user→viewer), 2FA helper round-trip.

Suite: 206 passed (576 assertions). Was 196.
