* refactor: added toBZZbaseUnit function * feat: added utility for attesting value is BZZ convertible to base units * fix: conversion from 15 to 16 decimal places, added unsafe versions * refactor: withdraw modal uses the safe conversion from BZZ * refactor: added BigNumber and Token class to handle BZZ digits correctly * refactor: extract deposit and withdraw functionality into single modal * test: added tests for Token * chore: removed unused component * chore: addressed PR review, token decimal is now integer 0-18 * chore: added comment to clarify the value restriction on token amount
