- Remove leasePeriod, as the dateTime (starts and end) can be derived either from the block timeStamp itself or (for future blocks) from the head block difference.
- Use Unix Epoch time as timestamp for leasePeriod starts and end (is starts necessary ?)
- Use leasePeriod in Parachain and Auction models
- Shift the deposit, raised, etc. values (expressed in planck) to their token decimal values (?)
