morfPhoto 0.15.0

• GET /api/v1/sources reports reachable for each pushed source: a bounded probe of the mount point (same availability_timeout_ms as the indexer, never a bare statvfs). Unlike mounted, it turns false when the source machine is off or its address changed, so PhotoHub can offer to reconfigure the access instead of failing silently.
• The privileged helper now classes mount.cifs "could not resolve address" as host_unreachable (it fell back to the generic cifs_mount_failed), so a client can retry a source by IP address after a hostname that the server cannot resolve.
