Lukas Brübach 875e87d1bc [DeckSync] Address auto-sync review: disconnect, backfill and modal conflicts
- Fail the run when the connection drops while a sync is running, and clear
  the active conflict, so the queue is not sent on a dead client and a
  re-login as another account never receives this profile's uploads.
- Backfill last_modified from upload_time in the 37 -> 38 migration and drop
  the "last_modified is null" arm from the sync-check query, so rows that
  predate the column stop reporting as changed on every poll.
- Skip conflicts during auto runs and report how many were skipped, instead
  of opening the modal conflict dialog from a timer or a file-watcher event.

-- Servatrice db migration from version 40 to version 41
-- Deck collection sync + versioning.
--
-- 1. Stable per-deck identity and change detection for two-way sync:
-- guid links a local file to its server row across renames, hash detects
-- content changes without downloading, last_modified drives newest-wins
-- default and conflict highlighting, deleted implements tombstones so a
-- delete on one device does not resurrect from the other.
-- 2. Limited per-deck version history: every hash-changing upload inserts a
-- row; the server prunes beyond the configured retention (default 20).
ALTER TABLE `cockatrice_decklist_files`
ADD COLUMN `guid` char(36) NULL AFTER `tags`,
ADD COLUMN `hash` char(40) NULL AFTER `guid`,
ADD COLUMN `last_modified` datetime NULL AFTER `hash`,
ADD COLUMN `deleted` tinyint(1) NOT NULL DEFAULT 0 AFTER `last_modified`;
-- Rows created before this migration only get a last_modified when a client
-- re-uploads them, so every sync check would keep reporting them as changed.
-- Backfill from the upload time once, here, instead of carrying a
-- "last_modified is null" branch in the poll query forever.
