What does this PR aim to accomplish?:

Reports if FTL is running on another port than 53 in the user-panel in the web interface. Additionally, the temperature info got its own line in the user-panel

Fixes #2030

Needs: pi-hole/pi-hole#4485

echo "<span id=\"temperature\"><i class=\"fa fa-fire ";

is now duplicated code. I'd rather put the if ($celsius >= -273.15) { further down to reduce duplication. Unfortunately, Github doesn't support suggestions if there are also lines deleted in a segment.

I imagine something like

<?php $tempcolor = "text-vivid-blue";
if ($celsius > $temperaturelimit) {
    $tempcolor = "text-red";
?><span id="temperature"><i class="fa fa-fire <? echo $tempcolor; ?>"></i> 
<?php if ($celsius >= -273.15) { ?>
  Temp:&nbsp;<span id="rawtemp" hidden><?php echo $celsius;?></span><span id="tempdisplay"></span>
<?php } else ?>
  No temp sensor found<span id="tempdisplay"></span>
<?php } ?></span>

(give or take some typos maybe)

I will test this once my review comments on the core PR have been discussed.

From my point of view, this is fine.

@bdoner

We added a new FTL API endpoint to query for the DNS port. If you want to continue to test, please run

pihole checkout ftl new/telnet-dns-port

Checked it out, still running on the tweak/web_status branches for core and web. All seems good :)

The icons should be optimized to get class fa-w and more padding but this is another thing for a follow-up PR. T think @rdwebdesign is already at it.

$pistatus is never a string

I will look at this after the completion of #2031.
