fix(#1601): remove mock MemPalace MCP block, restore Fleet API polling

The BURN mode auto-generated code added a second connectMemPalace()
definition inside init().then() that shadowed the real Fleet API
implementation. This mock used a non-existent window.Claude.mcp
interface and hardcoded fake stats.

Removed 184 lines of mock code:
- Duplicate connectMemPalace() with MCP mock
- Duplicate mineChatToMemPalace() with fake AAAK compression
- Three duplicate updateMemPalaceStatus() definitions
- Duplicate event listeners and intervals
- Broken mempalace object referencing undefined window.mempalace

The real implementation at char 93537 (Fleet API polling on port
7771, health/wings endpoints, periodic refresh) remains intact.
