* [DeckList] Add custom deck zones to the deck tree
Introduce user-definable zones nested under a board zone (main, side
or maybeboard) so players can organize cards inside a board without
changing board semantics.
- addCustomZone, renameCustomZone, moveCustomZone and removeCustomZone
manage zones. Names are unique across the whole deck and the standard
zone names (main/side/maybeboard/tokens) stay reserved.
- Board zones are created lazily on first use.
- getZoneObjFromName resolves custom names to their nested node so
addCard and XML loading route cards into them. Unknown names keep
creating legacy top-level zones.
- deleteNode keeps empty custom zones alive and only prunes empty
board zones.
- New deck_list_zones test suite locks hash parity with flat decks,
sideboard size accounting, maybeboard exclusion from plain export
and native-format round-trips.
