I’m using QGIS to map satellite imagery imported via the SentinelHub plugin. I’ve added a layer pinpointing active fires globally, which works fine over the satellite imagery. So far so good. Now I’d like to add labels and borders to better situate fires, say, currently in Turkey. When I import an Open Street Map layer, I of course have to place it over the satellite imagery for it to appear, at which point the sat imagery disappears. What I need is an Open Street Map tile type layer that only includes borders and labels that I can place over the satellite layer.

You don't have to save your annotations as a layer. Simply toggle the Text Annotation function in the toolbar and press Ctrl + T to switch it on/off. Your annotations will be saved within your project.
Well, you could use a program named MOBAC to create an Atlas of raster tiles at the Zoom you want by using the WMS of the basemap you selected. Since the data extracted is georeferenced this should be quite easy. Your basemap might even be included in the starter pack from what i see, so no need to tinker with some XML queries if you're lucky. Be carefull however, do set your output data and format right before using MOBAC. Make sure you've got my sqlite database as your output, i find it easier to load that way.
If the WMS isn't already set you'll need to go inside the mapsources folder inside MOBAC and create a new xml file containing the following informations:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<customWmsMapSource>
<name>Name inside MOBAC</name>
<minZoom>0</minZoom>
<maxZoom>18</maxZoom>
<tileType>TIF</tileType>
<version>1.1.1</version>
<layers>wanted_layer's_name_here</layers>
<url> Url of the wms </url>
<coordinatesystem>wanted output coordinates system</coordinatesystem>
<aditionalparameters></aditionalparameters>
<backgroundColor>#000000</backgroundColor>
</customWmsMapSource>
Another way to solve your issue is to simply use the function export as image built in QGIS to export your basemap visualisation, without the vector data you've applied to it, as a Tif tile.
Their has to be some faster way to do this thaugh.

The reason why your satellite image disapears is that both of your layers (OSM and Sentinel) are raster layers - for borders etc. vector layers are much better. You can obtain vector layers from OpenStreetMap via the QuickOSM Plugin for QGIS - the plugin is self explaining, all you need to know is the right tags for the OSM data. You can find help for the right tags here: https://wiki.openstreetmap.org/wiki/Tags
For country borders around turkey the query would be:
admin_level=2. See my example:Now, depending on your further analysis you are planning to do remove the polygon and point layer (so only the line layer representing the border is left). If you want to use the country as mask layer for further analysis you should remove all but the polygon and just style it so that there is no color shown filling the polygon (right click on the layer -> properties -> symbology)
