I'd return the thermostat and get any of a number of programmable stats that
don't require the common . Honeywell, White Rogers, and Robertshaw all make
them

The problem is the chattering sound. I already called customer
support and they said I needed to connect the common wire to the C
terminal, but I don't have a common wire. Only 2 wires, one red and
one white. I told them that and they said to "fish" a blue wire from
my boiler/transformer and connect it, but there isn't one.

I have the old thermostat back in place and the system works fine. I
just want to solve this chattering noise with the new thermostat so I
can use it.

disconnect thermostat disconnected completely. if the two wires are
touched together, your system should operate normally calling for heat.
if you separate the wires, the system should stop calling for heat.
looks like you're spending too much time on the wire colors. if room is
cold and RH closes across C as tested with the thermostat calling for
heat with your ohmmeter, you should also see that circuit open when the
thermostat is warm.
call that toll free service number in the morning.
