[DEPLOY-06] Implement Parish Management UI

[kilip]

Description

Build the Parish management screens. Data is seeded initially; this UI allows super-admin and parish-admin to manage parish records post-launch.

Subtasks

• DEPLOY-06-ST-01 Build parish list page at src/pages/setting/ui/ParishListPage.tsx
• DEPLOY-06-ST-02 Build parish create page at src/pages/setting/ui/ParishCreatePage.tsx
• DEPLOY-06-ST-03 Build parish detail/edit page at src/pages/setting/ui/ParishDetailPage.tsx
• DEPLOY-06-ST-04 Create thin exports at app/(dash)/setting/parish/
• DEPLOY-06-ST-05 Wire up Server Actions: create, update, soft delete
• DEPLOY-06-ST-06 UserRole gate: view (all approved), manage (super-admin, parish-admin)
• DEPLOY-06-ST-07 dioceseId required — dropdown from existing dioceses

Acceptance Criteria

• DEPLOY-06-AC-01 All three routes render correctly
• DEPLOY-06-AC-02 Only super-admin and parish-admin can create/edit/delete
• DEPLOY-06-AC-03 All authenticated users can view parish list and detail
• DEPLOY-06-AC-04 dioceseId dropdown populated from DioceseService.findAll()
