bert.hausmans b3eab6e0c8 feat(form-builder): add core services (schema, field, submission, value, field-access, locale, tag-sync, filter, webhook, anonymisation)
S2b Phase 1 per ARCH-FORM-BUILDER.md §20.2. Ten services + supporting
exceptions, jobs, and the organisations.default_locale column needed by
FormLocaleResolver. All services log via spatie/laravel-activitylog, write
operations are transactional, queued jobs are idempotent.

- FormSchemaService: CRUD, slug, version bump, duplicate, edit-lock,
  public_token rotation (7-day grace window), typed-confirmation delete.
- FormFieldService: CRUD, reorder, insertFromLibrary, binding-change guard
  (§6.5), conditional_logic + section cycle detection (§8, §4.8.1),
  is_filterable toggle triggers BackfillFormValueIndexedJob (§7.2, §22.10).
- FormSubmissionService: createDraft with idempotency, saveDraft (auto-save),
  submit with schema snapshot + signature hash computation (§9), review,
  delegate/revoke, soft delete. Fires S1 domain events (§17.1).
- FormValueService: bulk upsert with FieldAccessService RBAC (§24.2),
  Pattern A/C entity mirror writes (§6.1, §6.6) with cross-entity graceful
  skip for person.user_id=null.
- FieldAccessService: canRead/canWrite/filterVisibleFields honouring
  role_restrictions + subject-self (§18.3, §24.1).
- FormLocaleResolver: submitter → schema → org.default_locale → 'nl' (§16.2).
- FormTagSyncService: rebuildForPerson — replaces legacy TagSyncService
  deleted in S2a (§31.10).
- FilterQueryBuilder: generic filter applier for entity_column / tags /
  form_field sources (§7.4–§7.5).
- FormWebhookDispatcher + DeliverFormWebhookJob: HMAC-signed delivery with
  SSRF protection, exponential backoff {1m,5m,30m,2h,8h}, max 5 attempts,
  dead-letter on exhaustion (§17.5).
- FormSubmissionAnonymisationService: per-field anonymisation with separate
  activity log entries (§13.3, §23.4).

MigrationRollbackTest: pin the S2a drop migration by filename so future
migrations don't shift the step offset.
