Don't forget that velocity, and therefore momentum, is a vector. As
the heat input is converted to kinetic energy of the gas molecules, the
overall effect looks like "pressure" because the vectors all point in
random directions, so the overall velocity (and momentum) of the
container as a whole is still zero. Momentum is preserved.

The only way to "convince" an atom to move in a certain direction is
by giving it momentum stolen from something else. Magnetic fields
aren't enough: a magnet might attract an ion, causing it to move toward
the magnet, but it also move the magnet a tiny bit toward the ion in
proportion to its relative mass. For one ion, you won't notice this,
but if you try to move a significant mass, you're trying to pull a
car with a magnet mounted on the car.
You can't get away from needing reaction mass if you really want to
go from point A to point B. Something like Lorrey Drive will let you
wiggle around point A for a while, but that's of limited use.

I don't think tunneling violates conservation of momentum, but I may
be mistaken about that. If it does, that very well might be used to
get around some of the reaction mass problem--but a more likely way it
will be done is with the big scoop to suck up stray hydrogen atoms
along the way to push out the tailpipe.
