Search shortcut (S key) does not respect keyboard layout

### Description

see: #719
I would like the previous behaviour as I use an alternative keyboard layout (colemak) so it is confusing that the `S` key is actually `R` on colemak

A configurable option such as `use-layout` that reverts to the previous behaviour before https://github.com/Zykairotis/glanceXags/commit/399736fb98bced104298acd08f312285c353e14c , which is disabled by default (current behaviour) is a solution.

Start by reading issue #719 and commit 399736fb98bced104298acd08f312285c353e14c to understand the previous keyboard-shortcut behavior. Locate the search shortcut handling, then verify that the configurable layout option preserves the intended S-key behavior for alternative layouts while keeping the current default.
