patchmon: render byte counts without exponential notation (7.0.1+up2.1.3)

The null-safe fallback helpers from #99 pass values through fromYaml, which
parses every number as float64. Go's "%v" switches float64 to exponential
notation from about 1e6 upwards, so a bare byte count like 1048576 reached
multiplyQuantity as "1.048576e+06" and the render aborted with

  unsupported resource quantity suffix "e+06" in "1.048576e+06"

The same "%v" sits a second time on the output of a non-integral product,
where it never passes the suffix check — a fractional limitFactor together
with a bare number rendered a silently invalid quantity ("1.4999985e+06")
that only the API server rejects on apply.

Both call sites now go through a new patchmon.formatNumber helper, which
forces decimal notation for float64 and passes strings ("512Mi") through
untouched. This is the canonical fix agreed in #157, taken over verbatim
from template-chart with this chart's define prefix, so multiplyQuantity
stays the same copy in every chart.

Teil von #157.
