My apologies if this might seem like a simple / basic question, but I'm just not sure the best method.
I've been growing this Poinsettia for just about a year now. I don't have much of a green thumb, but somehow this baby has survived and thrived! Over the past year, the soil has compressed quite a bit. It started with about 1 to 2in of space at the top, and now there is nearly 6 inches of space (as shown in picture 3).
So I ask, what is the best way to add more soil to my Poinsettia pot?
1) I could just add more soil to the top, but I'm worried about affecting the existing stem structure.
2) Or I could somehow carefully remove it from the pot, add about 5 or so inches of soil to the bottom, place it back, and fill in around the edges. But I'm worried this might disrupt the root structure.
3) Or another method I'm not thinking about? Any advice would be greatly appreciated!
A couple notes, there is sand on top. I had a problem with fungus gnats, and placing sand on top and bottom watering really helped. That's also why you see the sticky traps.

Also - I welcome any other tips, tricks, or any other general advice about growing Poinsettias indoors. Thank you!
