proclamation-categories: sub-category management inline in parent form

- Registry: Remove 'parent.name' from listFields (all shown records
  are top-level with no parent), remove 'parent: true' from include
  since unused
- +page.server.ts: Custom load filters to parentId=null (top-level
  only); custom upsert syncs children (create/update/delete) and
  handles P2002 duplicate-name errors; custom delete cascades to
  children first to avoid FK constraint violations
- CategoryForm.svelte: Replace parentId select dropdown with dynamic
  list of sub-category inputs. Each row has a name field and Remove
  button. Pre-populates from record.children when editing existing
  categories. Add Sub-category button appends new rows
- +page.svelte: Remove unused relationOptionsData prop from
  CategoryForm; rename submit button label from 'Update' to 'Save'
- prisma: Add ProclamationCategorySubscriptionLevel join table
  migration and regenerate client
- General: Update TipTap mock, Toast, license-keys page, proclamations
  server/route tests, README, AGENTS.md, and other admin forms
