Add global app config with dashboard #42
Description
App may have a config dashboard, accessible (likely) with Admin privileges, where some global settings could be changed, for example:
- maximum product rating value (currently hard coded to 5)
- product categories (currently set via
/src/middleware/routes/api-users.tsfile) and their nesting level - delay time for expiring User registration confirmation token (currently hard coded to 1 hour)
- payment options (currently they are based on PayU API with some hard coded exclusion in
src/middleware/helpers/payu-api.tsfile)
