Description

When running Manual Backup with multiple sources configured, only the primary/first source is backed up. The other sources are silently ignored.

Root cause (from code review)

BackupManagementSection.tsx:152 calls /api/device/backup?save=true with no sourceId parameter. The backend endpoint (deviceRoutes.ts:46) accepts an optional sourceId and falls back to resolveSourceManager(undefined) — which always returns the primary meshtasticManager singleton — when none is provided.

The backend supports per-source backup, but the UI has no source selector and never passes a sourceId. Multi-source setups have no way to back up non-primary sources at all.

Steps to reproduce

1. Configure two or more Meshtastic sources in MeshMonitor
2. Go to Settings → Backup → Manual Backup
3. Click the backup/download button
4. Observe: only the primary source's config is included in the backup

Expected behavior

Either:

• A source selector in the Manual Backup UI allowing the user to choose which source to back up, or
• An "All sources" backup that iterates over all configured sources and bundles them together

Version

MeshMonitor v4.12.0-rc1
