bug: Fix paste issue in `$('input#network').on('paste'...)`

[ranma2913]

$('input#network').on('paste', function (e) {
    let pastedData = window.event.clipboardData.getData('text')
    if (pastedData.includes('/')) {
        let [network, netSize] = pastedData.split('/')
        $('#network').val(network)
        $('#netsize').val(netSize)
    }
    e.preventDefault()
});

First I noticed that my pasting data was being blocked most of the time. Appon analysis I found the issue was likely due to not trimming the pasted value. When double/tripple clicking a row in MacOS there is frequently a trailing whitespace of some kind which would end up causing the validation to fail.

Not to mention the preventDefault call was executing even when the pastedData didn't have a '/' char.

Also I get warnings about:

• javascript:S1874 Deprecated APIs should not be used
• CWE-477 - Use of Obsolete Functions.
