[Bug Fix] GLAA fix after database.cpp updates

[neckkola]

Description

Group LeadershipAA was not being sent to clients correctly after the database.cpp updates and changes to use the repo pattern. Issue was traced to saving the leadership aa data to the group_leaders table. The repo was converting to a std::string and was truncating at the first 0x00, creating the issue.

Solution:
Create an encode/decode function within Database to add char('0') to the values, mirroring the builtin behavior of the RoF2 client in various places. Therefore, the the repo treats it correctly. Also, rewrote the save routine to also use the repo and this functionality. There are no db changes required, the existing blob datatype remains unchanged.
