[Stub] Sandbox mode for Tourney

If a Sandbox mode, and a practice raid mode, is implemented, replace the two rest days between Tourneys with 48 hours of registration mode and 24 hours of qualifiers with ten tourney energy.

The 48 hours of registration mode would allow teammates to model the Tourney rules in sandbox mode, and practice raid mode, to adjust their teams.

The 24 hours of qualifiers would give ten tourney energy to fill Wanted Hero Mission Chests while testing defense and attack teams for seeding when Battle day One starts. At the end of 24 hours of qualifiers an account’s laurels would be reset.

The additional 72 hours of data mining would let Devs hot fix some bugs before Battle Day One.
