Close the remaining ways an accepted import fails to restore

Imports no longer accept the cutscene controller, which needs waypoints
to restore. Logistic filters and the basic item stack fields now have the
types and limits Factorio enforces, and the inventory summary skips
malformed items and counts repeated exported items once instead of
expanding them.

Lua's JSON loses precision past 2^50, so a generation there could no
longer be counted up and uploads were discarded. Imports now start over
from generation 1 when the stored or imported generation is at that limit.
Instances holding a copy from another epoch take the stored generation
instead of keeping their own higher one when there is no data to download.
