mcp: drop project-scoped paperless from .mcp.json (paperless is now wizard-only)

Paperless is a personal tool for wizard, not shared. It was project-scoped in the
infra repo's .mcp.json (the in-cluster paperless-mcp proxy), so every user whose
~/code IS an infra clone (emo, ancamilea) auto-loaded it. Per request, paperless
should be wizard-only: wizard now runs his own direct, token-based paperless MCP in
his user-scope config (a local barryw/paperlessmcp container -> paperless-ngx).
Removing the shared entry so emo and other infra-clone users no longer get it; the
`ha` MCP stays project-scoped. emo's clone drops it on next freshen.
