I have had this issue a few times with bathroom fans. I have no idea why the manufacturers don't just let us screw the fans in. The retaining clips are crap, sometimes don't hold well and often are never snug when they do. Yours is really bad so I am thinking it is not in the right spot. You usually have to hold the clips together and push up. A first ...

As long as ...

You could cut the trunking to fit the run you want, enclose the wires and then use simple wire loops around the trunking in two or three places, held close to the wall ...

Ceiling joists don't necessarily hold up the walls. What they do is prevent the outward force of the roof pushing the walls out. The joists 'pull' the outward forces together canceling them out so that the only force on the walls is then downwards. Whether your walls are stick frames or masonry, they're strength is in compression from downward forces ...

Expanding foam such as Great Stuff would work fine.

Silicone caulk would probably work the best with moisture and temp changes. You need to figure out how to push it up on the back side.
