"libcamera-still -t 55000" would run preview for 55 seconds and then take a still (although it isn't given a filename to save it to).
Do you get any debug information out of the application saying it has timed out or anything?
Your use of libcamera-still is also slightly worrying as the apps were all renamed quite some time back to rpicam-[still|vid|hello] because they aren't generic libcamera apps. Symlinks were left in place to handle legacy users, but if you're using Bookworm then using the native names avoids confusion.
Overrides for the overlay are defined in the README, or can be read with "dtoverlay -h imx415". clock-frequency and link-frequency are the two. Slightly strangely on this sensor the link frequencies supported vary based on clock frequency, so you do have to change both. IIRC "dtoverlay=imx415,clock-frequency=371250000,link-frequency=445500000" are the correct options for a 37.125MHz clock.
