Implement SQLite Store using gorm and relational approach (#1065)

Restructure data handling for improved performance and flexibility. 
Introduce 'G'-prefixed fields to represent Gorm relations, simplifying resource management. 
Eliminate complexity in lookup tables for enhanced query and write speed. 
Enable independent operations on data structures, requiring adjustments in the Store interface and Account Manager.
