[CardDB] Keep parse-time set filtering and bust the cache on enablement changes (#7448)
The parsers keep dropping printings for disabled sets so that disabling a
set hides them everywhere, not just in deck editor search. The cached parse
output therefore depends on enablement, which the source hash did not cover:
the first parse froze whatever enablement state existed at that moment and
later toggles hit the stale cache.

- Fold a parser schema version and the sorted enabled set names into the
  binary cache source hash so toggling a set or enabling newly discovered
  sets (including custom ones) forces a re-parse on the next load.
- Harden the legacy set migration to only write keys that exist so missing
  legacy values can no longer clobber cardDatabase.ini and silently disable
  sets on upgrade.
- Make CardDatabase::reloadCardDatabasesAndNotify() bypass the binary cache
  so an explicit reload always re-reads the files on disk, even when their
  size/mtime hash still matches.
- Cover cache invalidation end to end: sandboxed loads assert that disabling
  a set, adding a custom database and enabling a fresh set each rewrite the
  cache, that a no-op load keeps it, and that an explicit reload picks up
  edits the source hash cannot see.
