feat(ui): stacked resize (#3957)

* work

* tests and initial notes for refactoring

* refactor(stacked-panes): break out pane

* vertical functionality working with a single stack

* refactor: break out pane from stack

* fix: properly support multiple stacks in tab

* combining multiple stacks vertically

* vertical resizing working for all cases

* base functionality and tests

* some UX tweaking

* final functionality for directionless stacked increase

* some cleanups

* moar cleanups

* refactor: stacked resize

* fix: issue where resizing stacked geoms to 0 would cause them to overflow afterwards

* fix: handle uneven stacking

* functionality with tombstones

* new open new pane functionality

* match decrease increment behavior to increase one and fix some issues

* set fullscreen if maxed out

* allow splitting stacks

* fix tests mostly by parameterizing stacked_resize

* add tests

* some cleanups

* style(fmt): rustfmt

* add to config

* disable ci cache

* is_stacked => stacked

* docs(config): remove duplication
