Replacing more Long by types

[Arthur-Milchior]

Also renaming dcid to DeckConfId which is more Kotlin-like.

Also dealt, separately, with collection of longs

Those IDs were not found by the initial simple search. For those, I had to look at context to verify which type is appropriate

batch of conflicts on this one

[Arthur-Milchior]

Thanks. I added a constant for intent key so that at least it'll be certain to always be consistent

[david-allison]

Lint is failing

[BrayanDSO]

And... there are new conflicts

[mikehardy]

Another conflict, and may take yet one more when JSON object nullability refactor goes in
