It checks if you have all the lvl 10 items in your iventory and if you have enough currency.
Then your character progress gets reset and inventory cleared of the items of that character.
then you get the prestige reward added to your inventory and the prestige lvl of the character goes up
The endpoints checks if you can afford the item and have completed the required challenges when any exist.
It also throws an error if you try to buy an item you already have in your inventory.
Implemented tracking the progress of Signature challenges.
Also implemented both challenges Endpoints "getChallenges" ans "getChallengeProgressionBatch".
For "getChallenges", we just return an empty array since we dont need weekly and dailies yet.
- Moved initOrGetGroup and updateMetadataGroup into own MetadataController.php becauseits really big and cluttered the PlayerController.php
- Added Challenges and pciked challenges for the characters
- Added that when the game sends us an update for the Character metadata, it automatically creates unknown challenges in the database and sets the picked challenges for this characterData
