Record what a collectible pickup does not reach

The grant is withdrawn. A pickup resolves to a stackable profile item in bucket
7, not to a lore book, so inserting that row was never going to produce the
unlock the game performs. It also committed outside any transaction, so nothing
was pushed to the client and a successful grant was invisible.

Discovery is not a flag on the collectible row either. Every aligned halfword of
all 184 bytes across 5181 rows was resolved against the account flag map, and
the only offset that resolves widely is 0x2C, the item definition index already
read: item indices fall inside the flag slot range and resolve by coincidence.

What survives is the identification, which is verified: a pickup names its
collectible, the same one repeatedly, and a different one differently.
