Subject: [PATCH] Add gallery folder and sort order controls (#3605)

* Add gallery folder and sort order controls
Closes #3601

* Refactor sort constants to use Object.freeze for immutability

* Add comment

* Remove excessive null propagation

* Update type hint for gallery.folders

* Use defaultSettings.sort as a fallback

* Throw in groups

* Handle rename/deletion events

* Merge init functions

* Fix multiple gallery file uplods

* Add min-height for gallery element

* Fix gallery endpoint not parsing body

* translatable toasts

* Pass folder path in request body

* Change restore pictogram

* Add title to gallery thumbnail images

* Allow optional folder parameter in image list endpoint and handle deprecated usage warning

* Add validation for folder parameter in image list endpoint

* Add border to gallery sort selection

* Remove override if default folder is set to input

* Use server-side path sanitation

* Sanitize gallery folder input before updating
