Summary

Bugfixes "Fix blind throw while peeking up/downstairs"

Purpose of change

To fix #49009
We were only able to look around when peeking upstairs or downstairs because game::peek() function in

did not call game::peek( const tripoint &p ) when a z lvl move was detected, and instead call look_around() with no support for peeking.

Describe the solution

Remove look_around() handling in game::peek() when there is a z-lvl move, and let game::peek( const tripoint &p ) handle this.

Describe alternatives you've considered

Merging game::peek() and game::peek( const tripoint &p )

Testing

Done so far :

• peeking without changing z-lvl, then blind throw.
• peeking with a forbidden z-lvl change ( no stairs ) -> you can't climb there / You can't go down there.
• peeking upstairs ( ladder ), then cancel.
• peeking upstairs, then blind throw.
• peeking downstairs, then cancel. Peeking downstairs, then blind throw.
• peeking without changing z-lvl, then blind throw aiming z-lvl+1 through a solid floor. ( The interface looked like a normal throw through z-lvl )
• peeking upstairs, then blind throw aiming aiming z-lvl+1 through a solid floor. ( So aiming 2 z-lvl above what was the player position before peeking )
  The last two test were to make sure we can't throw at a position we should not be able to.

To do :

Additional context

I would love someone to double check I did not broke anything or/and propose more tests for me to do before this is merged.
The player avatar do weird "blink" moves during the blind throw, but they were already present before this PR. ( example, if we peek left, select blind throw, the player get back to its previous position to select the item to throw, then get teleported back to peeking position then we aim and throw )
