Lukas Brübach 8d0468402e [DeckSync] Match server rows by identity and hash the whole deck
Sync keyed local files to server rows by path, but the server names a row
after the deck, not after the file, so any deck whose file name and deck name
differ uploaded again on every run. A second pass then brought the server copy
back as an extra local file.

- Match by the sidecar's row id, then guid, then content, and only then by the
  server path, so renaming either side no longer duplicates a deck.
- Key the server tree by row id: the server allows several rows with the same
  name in one folder, and keying by path silently dropped all but one.
- Stop discarding rows whose name contains '/' ("U/W Control"). They stay
  matchable, and only the download file name is sanitised.
- Build the download path from the folder plus a sanitised row name, including
  every folder segment, so a hostile server name cannot escape the deck folder.
- Download a colliding server row under a unique name and count it, instead of
  skipping it without a trace.
- Hash the whole deck instead of the card hash: SHA-1 over the native deck
  string covers name, printings, banner, tokens and sideboard plans. The client
  and the server hash the exact bytes they exchange, so both agree.

Adds deck_content_hash_test for the client/server hashing invariant and for the
name-only change the card hash cannot see.
