Proposal Deposit does not accept decimal values

[0xpatrickdev]

If the minimum deposit is something like 0.00001, the UI will not allow the user to submit a deposit the form (only 0 and 1 are accepted). This is because step is hardcoded to 1, as it was assumed minimum deposits would also be at least 1.

Step should be calculated based on minDeposit:

cosmos-proposal-builder/src/components/DepositSection.tsx

Lines 50 to 57 in e21eb88

	<input
	type="number"
	min="0"
	step="1" // ensures integer
	name="deposit"
	id="deposit"
	ref={depositRef}
	defaultValue={minDeposit ? coinsUnit(minDeposit) : ""}

Similarly, toast banners do not show decimals. I think coinsUnit is also used here, so should fixing the above should solve this as well.
