Klaus Zanders 978b89121e Add multi-step "Allocate resource" dialog ...

Implement the dialog for creating a resource allocation as a two-step
Primer dialog driven by Turbo streams:

  1. Kind step: choose between an explicit principal and a
     filter-criteria placeholder.
  2. Allocation step: the per-kind form (principal/work package, date
     range, hours, filter name) swapped in without navigation.

Backend changes:
  - Controller `new`/`step`/`create` actions render and update the
    dialog via Turbo streams; entity and principal are resolved against
    the project and the user's visibility.
  - Add `principal_explicit` to distinguish an assigned principal from a
    named filter placeholder, with validations and a
    `needs_principal_assignment` scope on ResourceAllocation.
  - Add the `step` collection route.
  - ViewComponents and form objects under app/components and app/forms.
  - Locales for the dialog copy.

Add request, feature, and model specs covering the flow.
