feat: fix wizard step-skip bug + extend case edit with all fields + Paperclip title sync

- Fix keyboard navigation bug: React was reusing the submit button DOM element
  when transitioning "הבא" → "צור תיק", retaining focus and causing Enter to
  auto-submit step 3. Added key props to force element replacement.

- CaseEditDialog now covers all wizard fields: appellants, respondents,
  property_address, permit_number (in addition to existing title, subject,
  hearing_date, expected_outcome, notes).

- When case title changes, Paperclip project name is updated in background
  via new update_project_name() in paperclip_client.py.

- Extended CaseUpdateRequest, case_update MCP tool, and caseUpdateSchema
  to carry the new fields end-to-end.
