feat(forms): migrate all form definitions and configs to Nickel (.ncl)
Replace all TOML form definitions in examples/ and config/ with
  type-checked Nickel equivalents. Update cli_loader to prefer .ncl
  (via nickel export) over .toml in config search order.
  TOML support retained as fallback — no breaking change.

  - El loader usa nickel export --format json + serde_json como puente — evita reimplementar un parser Nickel en Rust y aprovecha el binario ya existente.
  - El orden de búsqueda .ncl > .toml permite migración incremental: cualquier config vieja sigue funcionando sin tocarla.
  - Los contratos Nickel (| default, | String) en los configs sustituyen la validación que antes era implícita en el parsing TOML — el error llega antes (en nickel export) con mensajes más descriptivos.
