Check account balance before publishing tx

[brusherru]

Before allowing to publish transaction it checks for the projected account balance.

It checks the sufficient balance for:

• any tx: to pay a gas fee from current account
• spend: to have spend amount + gas fee available
• drain: to have enough funds on vault account (if it is "local" address, otherwise it allows to send a tx)

It also shows a bit different red text on the confirmation page in case if some of the conditions does not pass:

• Waiting for gas estimation...
• You have insufficient funds to pay for gas
• You have insufficient funds to send this amount
• The vault has insufficient funds to be drained

Please double check:

fill the details of the tx (exceeding the balance) and hit next,
it shows properly that the tx cannot be processed, all good here
hit back
use delete/backspace to remove input in the gas price field
it throws:

I checked the prod and it's all good there, so it apparently is smth with this PR

Was your intention to display the "insufficient funds for gas" in case the balance is enough to cover the tx amount but the gas fee exceeds the available balance?
Cause now these lines work only in case the gas is the only thing to pay (spawn), but in the regular tx only the "insufficient funds to send this amount" is displayed.
If it's intended to be like that then it's ok, IMHO no need to overcomplicate these alerts, it's just that the PR description left me a bit hesitating about the intent

Got the same after some playing with numbers. Initially it worked.

Well, it will be shown for any transaction, when the balance is not enough to pay for a gas. Including the spend tx.
For example, try to send 0 SMH with 10000 Smidge / unit of gas price from the same test account (with 0.001 SMH), and you'll get this error message.

However, for spend tx there is additional condition, that checks that balance is equal or greater than amount + gas. And if it is not — then it will show "insufficient funds to send this amount". Basically it means that you have enough to pay for gas, but you should send less :)

Cannot get the same error.

Minor things
There are 2 messages:

• You have insufficient funds to send this amount
• You have insufficient funds to pay for gas

And Wallet shows the first one when amount is enough, but gas fee is bigger than the rest of the balance.
Balance 19.7
Funds to send 19
Gas fee: 3.6

And message "insufficient funds to pay for gas" appears only in the case when Gas fee is bigger than balance.
One of the option is to have only the first message for all cases.

Gas price also allows (and keeps) values like 00100
