Fixed web client GMCP handling for new modular structure

Added:
  - Field mapping from new GMCP structure to expected flat format for
Room data
  - Room.Info.Basic fields (id, coordinates, area) mapped to Info level
  - Room.Info.Exits converted to exitsv2 format with dx/dy/dz delta
fields
  - Comments explaining why mapping is necessary for Room handler
compatibility

Changed:
  - Room.Info.Basic and Room.Info.Exits handlers to create flat data
structure
  - Room handler triggers to check for mapped fields instead of nested
objects
  - Vitals handler to use new field names directly (health,
spell_points)
  - WebSocket connection to detect https protocol for wss://
