server: database improves:

- fixed broken database in some use cases (example: AI and choose name dialog, related to #11285);
- added docs and debug tools for sql queries, caches and memory analyse (see DebugUtil);
- refactor code to use shared settings;
- deleted outdated and un-used code (db logs, stats, etc);
