Store data in addon_config so it persists across reinstalls (#10)

* Store data in addon_config so it persists across reinstalls

Moves MeshCentral data, backups and recordings from /data to /config
(the addon_config mapping, /addon_configs/<slug> on the host). Unlike
/data, this folder survives add-on updates, rebuilds and uninstalls,
and is reachable via the Samba addon_configs share. Includes a
one-time migration from the old /data location.
