MCP: add bizMonitor server, align ops/topology tools, harden CLI exec

- New packages/netx-bizmonitor-mcp: 8 read-only cutover/biz-state tools
  mirroring the netxops bizMonitor group.
- Align netx-mcp (15) and netx-topology-mcp (16) with backend HTTP
  contracts; surface partial batch failures as tool errors.
- CLI hard gate: single-line show/display only; exec job IDs, path
  containment, owner and ne:exec checks.
- Cisco IOSv collection: stable prompt/echo handling over CR.
- Remove legacy netx_api/mcp and mcp_server.py; add mcp.all.json;
  sync skills and docs.
