Phase 1: TypeScript foundation in scripts-v2/

Create the complete TypeScript foundation for the Vue 3 migration
in a parallel scripts-v2/ directory. 72 files, 5430 lines, zero
any types, strict mode.

- types/ (21 files): Domain interfaces for all 17 entities derived
  from actual Laravel models and API resources. Enums for all
  statuses. Generic API response wrappers.
- api/ (29 files): Typed axios client with interceptors, endpoint
  constants from routes/api.php, 25 typed service classes covering
  every API endpoint.
- composables/ (14 files): Vue 3 composition functions for auth,
  notifications, dialogs, modals, pagination, filters, currency,
  dates, theme, sidebar, company context, and permissions.
- utils/ (5 files): Pure typed utilities for money formatting,
  date formatting (date-fns), localStorage, and error handling.
- config/ (3 files): Typed ability constants, app constants.
