feat: move off of systems.json and move Systems and SystemWaypoint into database

[eseidel]

This also removes FileSystem from all arguments.

What was previously SystemsCache is now SystemsSnapshot
and a new class "SystemsStore" is now just a wrapper around
db apis.

SystemRecords (just symbol, type, x, y and waypointSymbols)
are stored in one table, and SystemWaypoints are stored in
another.

Attempted to move most places off of using SystemsSnapshot
when possible, but there are still many more that can move.

Probably SystemsSnapshot splits into SystemRecordSnapshot
and SystemWaypointSnapshot, but for now it's combined.
