Throwing accuracy in the sidebar does not seem to account for throwing skill.

### Describe the bug

When throwing at enemies with some level of throwing skill, the sidebar lists hit chances in the low single-digits despite actual testing hitting almost 90% of the time. This does not seem to apply at 0 throwing, where you do miss about as often as the sidebar indicates. The problem exacerbates at higher levels. It seems the sidebar accuracy might not be taking throwing skill into account.

### Steps to reproduce

1. Spawn a debug monster some distance away (5-10 tiles works).
2. Spawn a bunch of rocks. Wield them and set their hotkey to 't' to speed up testing.
3. Set display style to "numbers" instead of "bars" in the options menu for a more accurate readout.
4. With throwing skill at 0, aim a throw. Note the hit chance is only around 3-4%, with 95% miss chance.
5. Throw a bunch of rocks, note that almost all miss.
6. Set throwing skill higher, e.g. around 4.
7. Aim a throw: note the hit chance has barely changed.
8. Throw a bunch of rocks: note that you're now hitting the majority of your rocks.
9. Set throwing to 10.
10. Aim: Note hit chance is still showing the same values as throwing skill 0.
11. Throw a bunch of rocks, note that you're now almost always getting regular or good hits.

### Expected behavior

I expect the hit chance readout to give an accurate representation of my chance to hit.

### Screenshots

My listed chance to hit (at 10 throwing)
The result of 10 thrown rocks.

### Additional context

_No response_

Reproduce the sidebar readout and actual rock throws with throwing skill set to 0, 4, and 10, following the issue's debug-monster steps. Trace the calculation used for the displayed hit chance and compare it with the throwing result; done means the sidebar changes appropriately with throwing skill and matches observed accuracy, with regression coverage for the discrepancy.
