feat(inventory): enforce DeletionRestrictions when deleting items

Deleting an item now follows its ItemComponent delResIndex row in the
DeletionRestrictions table, the way the client's shared inventory code
decides it (LWOInventoryComponent_Common::CanRemoveFromInventory @
0x00ce0d20, CheckDeletionRestrictionIndex @ 0x00c94c20):
- missing, unrestricted, unknown-type or empty rows allow it;
- LOTS_INCLUDED: another item of any listed LOT must remain;
- LOTS_EXCLUDED: other items of every listed LOT must remain;
- ANY_RESTRICTION / ALL_RESTRICTIONS: any / all listed rows allow it;
- ZONE: only in the listed maps; ALWAYS_RESTRICTED: never.
Operators (GM level 9) may delete anything, as in the client. A refused
delete is logged and the item stays.

ItemComponent.minNumRequired is not used: the client never reads it, so
its meaning can't be verified.

Issue 960: the rocket (6416, row 8) and the classic rocket parts (rows 1-3)
have rows that keep at least one rocket or part, so the last rocket can
no longer be deleted and strand the player.
