feat(subscriptions): auto-sync FY subscription row when dependent is activated

SubscriptionSyncService::syncForDependent() inserts a pending subscription
row for the current financial year whenever a spouse, child, or temporary
member becomes active. Triggered via two paths in Subscriptions bootstrap:

- Cashier path: spouse.fee_paid / child.fee_paid / temporary.fee_paid
- Zero-fee path: *.added events where fee = 0 (immediate activation)

Guards: member must be active + non-exempt type; dedup prevents duplicates.
Rates resolved identically to SubscriptionGenerator (year-specific catalog
code → generic code → hard fallback). Never throws — safe in event context.

+### 5.1b Real-Time Dependent Sync (SubscriptionSyncService) — Added 2026-07-18
+
+When a spouse, child, or temporary member is activated (either immediately because fee=0, or
+after the Cashier processes their addition fee), a subscription row for the **current financial
+year** is automatically inserted for them.
+
+```
+Trigger A — fee paid path (Cashier dispatches):
+  spouse.fee_paid   → SubscriptionSyncService::syncForDependent('spouse', $spouseId, $memberId)
+  child.fee_paid    → SubscriptionSyncService::syncForDependent('child',  $childId,  $memberId)
+  temporary.fee_paid→ SubscriptionSyncService::syncForDependent('temporary', $tempId, $memberId)
+
+Trigger B — zero-fee path (controller dispatches *.added with fee=0):
+  spouse.added   (fee=0) → syncForDependent('spouse', ...)
+  child.added    (fee=0) → syncForDependent('child', ...)
+  temporary.added(fee=0) → syncForDependent('temporary', ...)
+
+syncForDependent logic:
+  1. Guard: member must be active + not an exempt membership type (honorary/seasonal)
+  2. Dedup: skip if subscriptions row already exists (member_id + FY + person_type + person_id)
+  3. Resolve person name from the dependent's table
+  4. Resolve rate via service_catalog (year-specific code → generic code → hard fallback)
+  5. Apply year-specific discount if SUBSCRIPTION_YEAR_ADJUSTMENT_{year} rule exists
+  6. INSERT pending subscription row
+  7. Log success or catch + log error (never throws — safe in event handler context)
+```
+
+**Idempotent:** safe to re-fire; the dedup guard prevents double rows.
