fix: declare precision 9 on all conversion_factor fields

The Float control parses values with the field precision, falling back
to the global float precision when the docfield declares none
(frappe ControlFloat.parse / get_precision). On a site with float
precision 2, a fetched UOM factor of 0.453592292 was written back to
the model as 0.45, silently corrupting every derived quantity by 0.8
percent. A ratio must not inherit display precision meant for
quantities, so declare the same precision 9 the UOM Conversion Factor
master already uses on every transaction-level conversion_factor
field.

(cherry picked from commit 69a35a12cb)
