Note that when I boot from a Debian Trixie live image straight into
GNOME running from the thumb drive, I _am_ able to connect to the WiFi
network by opening the GNOME menu from the top right corner of the
screen and clicking on WiFi. So Trixie _is_ capable of connecting to
my WiFi using the controller in my new computer;

Without installing the firmware file you mentioned above ? It is not present in the firmware-iwlwifi package, so it should not be present in the live image either.
Correct, the Debian live thumb drive never prompts for for the firmware file and still successfully connects to the WiFi.

it's just that the installer isn't.

This may be a duplicate of bugs #1095302 and #1103993 (netcfg does not support Wi-Fi 7 devices). 
Quite possible, since I believe that the WiFi device provided by my motherboard / CPU combination is a WiFi 7 device. 

What is the wireless controller model ?
Can you do a quick test in the live system ?
Run the command "/sbin/iwconfig" and check if it reports wireless extensions on the wireless interface wl*. You need to install the package wireless-tools if the command is missing.

It reports "no wireless extensions" for the wlp131s0f0 device.
