Fix critical notification system bugs and security issues

Browse source 
This commit addresses multiple critical issues identified in the notification
system audit conducted with Codex:

**Critical Fixes:**

1. **Queue Retry Logic (Critical #1)**
   - Fixed broken retry/DLQ system where send functions never returned errors
   - Made sendGroupedEmail(), sendGroupedWebhook(), sendGroupedApprise() return errors
   - Made sendWebhookRequest() return errors
   - ProcessQueuedNotification() now properly propagates errors to queue
   - Retry logic and DLQ now function correctly

2. **Attempt Counter Bug (Critical #2)**
   - Fixed double-increment bug in queue processing
   - Separated UpdateStatus() from attempt tracking
   - Added IncrementAttempt() method
   - Notifications now get correct number of retry attempts

3. **Secret Exposure (Critical #3 & #4)**
   - Masked webhook headers and customFields in GET /api/notifications/webhooks
   - Added redactSecretsFromURL() to sanitize webhook URLs in history
   - Truncated/redacted response bodies in webhook history
   - Protected against credential harvesting via API

4. **Email Rate Limiting (Critical #5)**
   - Added emailManager field to NotificationManager
   - Shared EnhancedEmailManager instance across sends
   - Rate limiter now accumulates across multiple emails
   - SMTP rate limits are now enforced correctly

5. **SSRF Protection (High #6)**
   - Added DNS resolution of webhook URLs
   - Added isPrivateIP() check using CIDR ranges
   - Blocks all private IP ranges (10/8, 172.16/12, 192.168/16, 127/8, 169.254/16)
   - Blocks IPv6 private ranges (::1, fe80::/10, fc00::/7)
   - Prevents DNS rebinding attacks
   - Returns error instead of warning for private IPs

**New Features:**

6. **Health Endpoint (High #8)**
   - Added GET /api/notifications/health
   - Returns queue stats (pending, sending, sent, failed, dlq)
   - Shows email/webhook configuration status
   - Provides overall health indicator

**Related to notification system audit**
