feat: multi-source disk entries with chips display

diskUsage now carries Sources []string instead of a single Source.
collectDiskUsage accumulates all sources (samba, nfs, manual) per path.
NFS no longer adds a redundant label to used_by.

Dashboard and Settings render one chip per source. When a path
is shared via SMB and NFS, both chips appear.

API breaking: disks[].source replaced by disks[].sources[].
