improve: optimization of new shop (store)

[Nottinghster]

The main improvements implemented in the code are:

Cache System for Points:

* Added a cache system to reduce frequent database queries.
* The cache expires after 5 minutes to ensure that the data is updated periodically.

Optimization of Infinite Loop:

* Added a counter to limit the number of executions of the refreshPlayersPoints function.
* The counter is stored in GlobalStorage for persistence.

Single Initialization of the Shop:

* Implemented a check to prevent the shop from being initialized multiple times.
* This reduces memory usage and redundant processing.

String Construction Optimization:

* Replaced excessive concatenations with table construction and table.concat().
* This approach is much more efficient in Lua.

Event Consolidation:

* Created a unified updatePlayerShopData function to reduce the number of event calls.
* This reduces the overhead of scheduling events.

Cache Cleanup on Logout:

* Added a logout event to clear the cache when the player disconnects.
* This prevents memory accumulation from data of players who are no longer online.

Purchase History Limitation:

* Limited the purchase history to 50 records to avoid data overload.

Name Validation Optimization:

* Improved the efficiency of the validName function by using lookup tables and more direct checks.

This is the fourth (from game_shop) commit in less than five days. Could you leave the PR open for at least a week? That way, you can introduce future changes or whatever you have planned within seven days, and then it can be merged into the branch.

Just to keep the main repo commits cleaner.

I hope my comment doesn't bother you.
