through `user_id`, including API resources, validation, repository
support, and database migrations.
Introduce a two-step login flow that checks email first and lets users
without a password create one before signing in.
Update the employee detail UI with a dedicated user tab and refresh the
employee and intervention side navigation to support the new account
management flow.
Add price list management across the API, store, services, routes,
navigation, and sales views.
Support quotes for either a client or a client group, including PDF
download and nullable client validation for group-based recipients.
Extend client groups to manage assigned clients directly from the form
and detail views, and refresh supplier, intervention, stock, and order
screens with updated interactions and layouts.
