* balance: extract the bytes-aware density metric to weed/topology/balancer

The shell's volume.balance ranks servers by a bytes-aware density (used volume
equivalents over free capacity). Move that math into the shared balancer package
(VolumeDensity / DensityRatio / DensityNextRatio) so the maintenance worker can
adopt the same metric next. Shell behavior is unchanged.

* balance: rank a server with no free capacity as the fullest

DensityRatio/DensityNextRatio divided by capacity, so a server past its slot
limit (negative capacity) returned a negative ratio and sorted as the emptiest
under ascending consumers — the opposite of reality. Treat any non-positive
capacity (full, or overfull mid-run after receiving volumes) as the fullest
(+Inf) so it is a move source, never a target. Covered by negative-capacity and
ordering tests.
