Add uncompressed-size and new-chunk-size columns to snapshot list

Browse Source 
The remote snapshot table now shows the total plaintext size of all
chunks referenced by each snapshot, plus the plaintext size of chunks
newly referenced by that snapshot (chunks not in any earlier completed
snapshot known to the local DB). The latter is the marginal data
introduced by each backup — useful for spotting which snapshots
actually added bytes vs. dedup'd against prior state.

Both new columns are computed from the local database only. Snapshots
that exist in remote storage but not in the local DB show
"<remote only>" in those cells; their COMPRESSED SIZE column still
reflects the value fetched from the remote manifest.
