fix: MEMPALACE INIT shows real stats from fleet API (#1340)

Root cause: connectMemPalace() set placeholder values (0x, 0, 0B)
immediately and tried to connect to window.Claude.mcp which doesn't
exist in a normal browser. Never contacted the actual fleet API.

Fix:
- Replace connectMemPalace() to fetch from fleet API (/health, /wings)
- Show MEMPALACE CONNECTING during fetch, ACTIVE on success,
  OFFLINE if API unavailable
- Populate compression ratio, docs mined, AAAK size from real data
- Add formatBytes() helper for human-readable sizes
- Periodic refresh every 60s when connected
- Configurable API endpoint via ?mempalace=host:port query param
- Remove dead window.Claude.mcp mock code
