feat(16-automated-tasks): moduł zadań automatycznych — CRUD + watcher/executor

Reguły automatyzacji oparte na zdarzeniach (receipt.created) z warunkami
(integracja/kanał sprzedaży, AND logic) i akcjami (wyślij e-mail z 3 trybami
odbiorcy: klient / firma / klient+firma). Trigger w ReceiptController po
utworzeniu paragonu — błąd automatyzacji nie blokuje sukcesu paragonu.

+# Phase 16 Plan 02: Automation Watcher/Executor Summary
+
+**AutomationService: trigger receipt.created -> ewaluacja warunkow (integration) -> wykonanie akcji (send_email z 3 trybami odbiorcy).**
+
+## Performance
+
+| Metric | Value |
+|--------|-------|
+| Duration | ~15min |
+| Completed | 2026-03-18 |
+| Tasks | 3 completed (2 auto + 1 checkpoint) |
+| Files created | 1 |
+| Files modified | 5 |
+
+## Acceptance Criteria Results
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| AC-1: Ewaluacja warunkow | Pass | AND logic, integration_id check |
+| AC-2: Akcja send_email | Pass | EmailSendingService::send() z actorName |
+| AC-3: Odbiorca respektuje config | Pass | client/company/client_and_company |
+| AC-4: Trigger w ReceiptController | Pass | try/catch, nie blokuje paragonu |
+| AC-5: Logowanie automatyzacji | Pass | activity_type automation_email_* |
+
+## Accomplishments
+
+- AutomationService z pelnym flow: trigger -> evaluate -> execute
+- Bezpieczna integracja w ReceiptController (try/catch)
+- EmailSendingService rozszerzony o recipient override (backward compatible)
+- 3 tryby odbiorcy e-mail: client, company, client_and_company
+
+## Files Created/Modified

+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## Next Phase Readiness
+
+**Ready:**
+- Phase 16 complete — pelny modul automatyzacji (CRUD + watcher/executor)
+- Rozszerzalny: nowe typy zdarzen/warunkow/akcji = dodanie do whitelists + evaluator/handler
+
+**Concerns:**
+- Brak
+
+**Blockers:**
+- None
