Replace logo with client-supplied artwork; add Nablus workshop registration form

- public/images/logo.png replaced with the client's professionally-designed
  version, cropped to remove excess background margin (used sitewide via
  logo.blade.php / app-logo.blade.php / app-logo-icon.blade.php)
- New standalone, unlinked registration form at /forms/nablus-workshop for a
  one-off workshop Libra is co-hosting with Smart Business Center, replicating
  a ClickUp form the client previously used but with Libra's own branding.
  Submissions email info@libra.adv.ps and redirect to /about. No nav/footer
  link, no DB storage, no captcha (PRD v1.3).
- Tasks 17 (parent), 17-1 (Mailable + email template), 17-2 (page/route/form)
  taken through product-definition -> task-readiness -> dev-implement -> dev-qa,
  all Done. 11 new tests passing; full suite run clean of new regressions
  (69 pre-existing unrelated failures, documented in docs/tasks/17.md).

+## Description
+
+Parent container task for the standalone Nablus workshop registration form (PRD v1.3 update,
+Section "Update — Version 1.3"). This task carries no independent implementation — it is done
+when both subtasks below are Done.
+
+## Acceptance Criteria
+
+- [x] Subtask 17-1 is Done
+- [x] Subtask 17-2 is Done
+
+## Sub-tasks
+
+- 17-1 Registration mailable and email template
+- 17-2 Standalone registration page, form, and submit wiring
+
+## Completion Note (2026-09-27)
+
+Both subtasks Done. Full-suite regression gate run as parent rollup:
+`php -d memory_limit=4G artisan test | cat` — 1723 passed, 69 failed, 7 skipped. All 69 failures
+are pre-existing and unrelated to this parent's changes (About page scholarship section removed
+2026-01-11 per 16-6, plus Card/Accessibility/Admin-export/Availability-calendar tests); none
+reference routes/web.php, standalone.blade.php, or the nablus-workshop page. Not fixed here —
+outside this task's scope.
