Lock Sapphiron's Chamber in Naxxramas until all wings are cleared

This was a requirement up until Patch 3.3.0

Could this maybe be done through conditions?

Start by reading the linked AzerothCore pull request #15048 and compare its approach with this module's progression behavior. Identify the existing Sapphiron’s Chamber and wing-clearance entry points, then verify that the chamber remains locked until every Naxxramas wing is cleared; done means the lock and unlock behavior is covered by the project’s relevant tests or reproducible checks.
