* Fix off by small amounts in sent amount kaspa Floating point math causes inconsistencies when converting kas to sompi. Use a method that parses the amount as a string, the converts it to sompi then parse back to uint64 * Deal with SendAmount as strings all the way * Consistent config handling * Set variables directly from utils.KasToSompi Use = instead of := to ensure no shadowing * Fix validate amount regex * Use decimal places as defined by constants Also check if SompiPerKaspa is multiple of 10 * Minor updates for context clarity
