- Extract getServerTimezone() helper in timeUtils.js; apply it in
formatChartTime and formatLocalTimeOnly (previously ignored TZ)
- Status.js: remove local formatLocalTime (was bare toLocaleString),
import the shared util that reads server timezone
- SettingsWizard: immediately update localStorage when timezone is saved
so new value takes effect without waiting for cache to expire

Bugs fixed:
- Status page: autoRefresh checkbox now actually pauses the interval
- Dashboard edit modal: hide URL field for heartbeat resources (was always shown as required)
- Dashboard: apply items_per_page, default_sort, and refresh_interval from settings on mount
- Dashboard: call loadResources() immediately on mount (was waiting 15s for fallback)
- Observability: listen for WS 'metrics' messages so tab updates live, not just on poll
UX improvements:
- Dashboard: replaced window.confirm() with inline Confirm/Cancel buttons for single and bulk delete
- Dashboard: skeleton rows shown while initial data loads (no more flash of empty state)
- Notifications: WebSocket moved from window global to useRef; exponential backoff on reconnect
- Notifications: replaced window.confirm() with inline Confirm/Cancel for Clear All
- ResourceDetail: initial API calls run in parallel via Promise.all
New features:
- ntfy.sh push notification channel: enable in Settings, enter topic, get mobile push alerts
- Network Discovery: Actions → Discover Network scans LAN for reachable hosts, probes HTTP ports, and lets you add any found host to monitoring in one click

The app is a dark-mode design but all theme defaults were 'light'.
Once the theme setting was wired to data-theme, it applied light mode
overrides that turned the app background white while panels stayed dark.
- Changed all server-side theme defaults from 'light' to 'dark'
- Added data-theme="dark" to index.html so the correct theme applies
before React loads (eliminates any white flash on first render)

- maintenance_mode and hasActiveIncident are SQLite integers (0/1), not JS booleans.
{0 && <span>} evaluates to {0} which React renders as the text "0" in the DOM.
Fixed with !! coercion on both conditions in renderResourceRow.
- avgResponseTime can be NaN for resources with no checks (e.g. icmp with no data).
Added || 0 guard in the aggregate average and —/ms conditional in the row display.

Replace hard-coded white/light colors with dark theme palette matching the rest
of the app. Key changes: dark navy background (#1e293b/#0f172a), high-contrast
text (#f1f5f9 titles, #94a3b8 body), teal accent (#14b8a6) for active filter and
unread left-border, red (#f87171) clear button, dark scrollbar, subtle hover
states on items and action buttons.

- HTTP method + request body: GET/POST/PUT/PATCH/DELETE/HEAD selector and body textarea for http/health checks; stored in http_method/http_body columns; monitorService sends correct axios method+data
- Alert escalation: incidents open longer than escalation_hours get forwarded to fallback_webhook and marked escalated=1; hourly cron in scheduler
- Baseline-relative slow alerts: effectiveThreshold = response_time_threshold || (baseline * 2) — adaptive threshold without manual config
- Notification grouping: pendingAlerts collected per check cycle; ≥2 alerts flush as one grouped email+webhook; individual in-app entries still saved per resource
- Rate limiting: in-memory per-IP limiter (20/min heartbeat, 60/min status-page); no external package
- App.js split: Dashboard.js (monitors list + modals) and ResourceDetail.js extracted; App.js reduced from ~1987 to ~80 lines
- formatDuration moved to utils/timeUtils.js; imported by both new components
- DB migrations: http_method, http_body, incidents.escalated columns
- 18 passing API/unit tests (node:test, zero dependencies)

- Heartbeat type: cron jobs POST to /api/heartbeat/:token to stay alive; scheduler marks
them down if no ping is received within the configured timeout window
- Alert rules: per-resource consecutive_failures_threshold now respected in handleIncident,
overriding the global setting; GET /api/resources/:id/alert-rules endpoint added
- SSL cert expiry badge: dashboard rows surface days_remaining for TLS monitors, turning
orange at ≤30 days and red at ≤7 days
- Webhook payload templates: {{name}}/{{status}}/{{url}}/{{type}}/{{message}}/{{timestamp}}
variables interpolated before POST; Slack-compatible text wrapping as fallback
- Status page visibility: is_public column per resource; GET /api/status-page returns only
public resources; Status.js updated to use the new endpoint
