gotenberg: render large byte counts without exponential notation (8.0.1+up8.36.0)

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 turned into
"1.048576e+06" - not a valid Kubernetes quantity. multiplyQuantity then aborted
the render on its own suffix check. The second "%v", the one printing a
non-integer product, never reaches that check and rendered an invalid quantity
silently; only the API server rejects it on apply.

Both call sites now go through a new formatNumber helper that forces plain
decimal notation and passes strings ("512Mi") through untouched. The
fromYaml/toYaml round-trip is not touched: it was just unified across all
charts and it is not the cause.

gotenberg reaches multiplyQuantity from two places - the Deployment's
resources block and NOTES.txt, which reports the effective limits. With the
chart's default values both non-CPU resources carry an explicit limit, so no
limit is computed and neither site was affected in the default configuration.
