feat(projects): t-paliad-232 Verfahrenstyp picker + Schriftsätze CTA

Two-part fix from m's 2026-05-21 finding that the Schriftsätze tab
told users "Bitte zuerst einen Verfahrenstyp setzen" while the
project form had no field to set it. The `proceeding_type_id`
column was already on `paliad.projects` and accepted by the API.

  Part 1 — Verfahrenstyp picker on the case-fields block

    * frontend/src/components/ProjectFormFields.tsx — new optional
      <select id="project-proceeding-type-id"> rendered between
      Aktenzeichen and Mandantenrolle inside the type=case block.
      First option is "(nicht gesetzt)" / "(unset)".
    * frontend/src/client/project-form.ts — shared
      loadProceedingTypes() + populateProceedingTypeSelect()
      helpers. Options sorted by `code` (de.* → dpma.* → epa.* →
      upc.*). readPayload sends `proceeding_type_id` only when the
      user picked a value; prefillForm restores the saved id via
      dataset.preselect to survive the async populate race.
    * frontend/src/client/projects-new.ts — kicks off populate on
      DOMContentLoaded.
    * frontend/src/client/projects-detail.ts — edit-modal preload
      now awaits populate; the local loadProceedingTypes duplicate
      (used by the counterclaim modal) is replaced by the shared
      helper so both surfaces hit the same cache.

  Part 2 — Actionable empty-state on the Schriftsätze tab

    * frontend/src/projects-detail.tsx — the static <p> empty-state
      becomes a div with a "Projekt bearbeiten" button.
    * frontend/src/client/projects-detail.ts — openEditModal now
      accepts an optional focusFieldID; the new
      #project-submissions-edit-cta click handler calls it with
      "project-proceeding-type-id" so the picker is scrolled into
      view and focused right after the modal opens.

  i18n: new keys projects.field.proceeding_type{,.unset,.hint} and
  projects.detail.submissions.empty.no_proceeding.cta; reworded
  no_proceeding copy to match the new "edit the project" CTA.

  Backend already validates via validateProceedingTypeCategory
  (mig 087/088 fristenrechner-category guard). Added
  TestProjectService_CaseProceedingTypePicker exercising both the
  happy and reject paths through a `case`-typed Create.

Manual test path: open any case project → Edit → the Verfahrenstyp
picker shows below Aktenzeichen → save → the Schriftsätze tab now
lists the submission codes. Clicking the empty-state CTA jumps
straight to the picker.

-// Design choice — why not lukasjarosch/go-docx:
-// The library's "nested placeholder" guard treats sibling placeholders

-// refuses to replace either. Patent submissions routinely have multiple

-// is ~150 LoC and handles both the single-run common case and the
-// cross-run case (where Word may split a placeholder across runs after
-// editing).
+// Word .dotm (macro-enabled template), .docm (macro-enabled document),
+// .dotx (template, no macros), and .docx (document, no macros) are all
+// OOXML zip containers. The macro-bearing variants carry an extra set
+// of parts:
 //

+//   word/customizations.xml          — keyMapCustomizations
 //
-// Missing-value behaviour: when a placeholder has no binding in the
-// PlaceholderMap, the renderer emits a marker token so the lawyer sees
-// the gap in Word rather than failing the request. See §6.3 of the
-// design doc.

+// settings, document body, header/footer/numbering, glossary, custom
+// XML — passes through bit-for-bit at the original compression method
