- Admin: each endpoint with {vars} shows a vars config section; per-var
mode is "ask user" (bot prompts in WhatsApp) or "fixed" (preset: today,
month_start, month_end, last_7, last_30, year_start, or literal)
- Bot: resolves fixed vars before calling endpoint; queues "ask" vars and
collects them sequentially from the user before executing the report
- date_mode now uses fecha_desde/fecha_hasta (ERP expected names); added
current_month mode
- JSON responses from ERP (sin_datos etc.) shown as text, not uploaded as file
