feat(overlays): add/remove overlay from store

Description

This PR focuses on adding functionality to manage overlayBioEntity state for multiple overlays. Bio entities are stored under key-value pairs as follows: export type OverlaysBioEntityState = { overlaysId: number[]; data: { [overlayId: number]: { [modelId: number]: OverlayBioEntityRender[]; }; }; }; This way it's easier to add and remove new overlays.

Things done

• store management - adding / removing new overlays
• toggling on/off overlays in drawer -> currently displays only first overlay

Things to consider during code review

OverlayListItem covers test cases for useOverlay hook.
