Clutch fork won't clip back in.

I had the same problem on a buddies car when the fork bent while driving one day, and it would no longer disengage the clutch. I widened the access hole in the bellhousing with a carbide bit until I was able to get the new fork in enough for it to snap in place.

All you parts look dry. I always use a very thin film of Synthetic Disc Brake grease on the fulcrum pivot, the two pads that contact the throwout bearing and on the inner sleeve the throwout bearing slides on. I use just enough to get the job done. If you use too much, it will attract dirt and could possibly get on the clutch itself.

I also lube all the contact points on the clutch linkage after I blue print the linkage. I've never seen a linkage that did not need some massaging to get all the contact surfaces lined up to reduce misalignment of the linkages.
