I haven't started flying this itinerary yet.
And yet, MMB tells me that it is impossible to upgrade this segment online; and two calls to the BAEC call center yielded the same answer: talk to your travel agent. What am I doing wrong? Will my travel agent even be able to upgrade it on my behalf?

Your TA has no access to your avios so any UuA must be done with BA.
Ignore MMB - it often fails to do UuAs for anything but the simplest one way or return bookings. If there is reward availability on your flight for the cabin you want to upgrade to just call BA and do it over the phone.
