New Features :

- Added statistics page with Graphs and Charts on Desktop and Mobile where users can have an insight of their data. This fixes #35
- Added a little History of latest flows on HomePage on both Platforms. Closes #41
QoL improvemnts:
- largely improved the speed/performance when going to the ManageExpenditures pages on both Platforms
- Pratically removed the lag that exists when navigating from StatisticsPageM to ManageExpendituresM. Added a bool that will ensure that the Observable collections are not initialized on every navigation
- Added an event that will be listened and will be used to notify when OfflineExpendituresList is updated
- Probably other stuff that I forgot to mention
