Bookkeeper: Add Filtering dropdown to balance sheet and sats flow screens

[evansmj]

it would be great if there were more grouping/filtering options in the satsflow and the balance sheet, to see exactly how much money flowed into and out of each account, not just the entire node.

A new dropdown component is to be added to the balance sheet and sats flow screens next to the other dropdown components.

This component will be able to include and exclude event tags.

The event tags will be entered comma separated and whitespace trimmed for processing.

There will be a radio button to toggle between 'include' and 'exclude.

Given the 'include' radio button is selected, And I have entered tags in the text field, Then these event tags are the only ones that will be displayed.

Given the 'exclude' radio button is selected, And I have entered tags in the text field, Then event tags other than these will be displayed.

input 1: "paid_invoice, deposit"
input 2: "paid_invoice,deposit"
input 3: " paid_invoice,deposit"
input 4: "paid_invoice,deposit "

The event tags will be entered comma separated and whitespace trimmed for processing. The above inputs are all valid and have the same result.
