feat(124): sms templates CRUD + order picker

- Nowa tabela sms_templates (name + body + is_active) + minimalny CRUD.
- /settings/sms-templates: lista + formularz z paleta zmiennych (pill chips).
- Wydzielono Sms\SmsVariableResolver ze wspolna logika placeholderow;
  Email\VariableResolver staje sie cienka fasada — EmailSendingService bez zmian.
- Dropdown "Wybierz szablon" w zakladce SMS na /orders/{id} z fetch
  GET /orders/{id}/sms/template + OrderProAlerts.confirm przy nadpisaniu.
- Stopka SMSPLANET dalej doklejana wylacznie przez SmsConversationService
  (Phase 122 contract preserved).
- Sidebar Ustawien: nowy link "Szablony SMS".

Migration: 20260512_000112_create_sms_templates.sql (CREATE TABLE).
