* Add expand/collapse UI for reactions - Adds a CollapsibleFlowLayout for controlling the layout - Adds tests for this layout and some mocks for testing layouts generally - Improves the rendering of the reaction buttons which were not pixel perfect - Adds the UI for the expand collapse buttons including the count of hidden items in the collapsed state. * Add comment for reactionsCollapsed binding. * Remove Flow and simplify implementation - Remove SwiftUI-Flow - Add strings by importing from Localyse - Remove count on expand button as requires GeometryReader and can cause loops - Don't use GeometryReader for hiding reactions with opacity(just put them way off screen for now) - Fix unit and UI tests * Address PR comments - use synthesized inits - use rows rather than lines for naming flow layout - other naming improvements - reactions were already rendered in another ui test, removing my test on favour of those and updating the screenshots for those.
