Print full monster stat blocks with encounters

[Daren9m]

Problem

Printing an encounter currently prints only stat blocks the DM manually expanded. A table-ready printout should contain the complete stat block for every distinct monster in the encounter.

Acceptance criteria

• Printing an encounter includes one full stat block for every distinct monster.
• Stat blocks print even when collapsed in the interactive UI.
• Interactive expand/collapse behavior remains unchanged on screen.
• Duplicate monster quantities do not duplicate the same stat block.
• Print layout avoids splitting a stat block unnecessarily across pages.
