remove mempalace mcp permission grants and orphaned wing config

MemPalace retired 2026-07-28 (thin KG, never held a brand fact, empty
tunnel/hallway layer, junk in two of four palace rooms, and a single
test mine burned 20+ min CPU with no way to cancel it short of killing
the server). Replaced by decisions-ledger.md + current-state.md.
