feat: auto-load RIPS exams when patient is selected in recepcion

When a patient with a cedula is selected, the system queries RIPS
Manager for exams registered in the last 5 minutes. A green banner
shows the count with a "Cargar" button that pre-fills TomSelect.
Unmapped exam codes shown as a warning. Banner clears on deselect/reset.

- config.php: RIPS_MANAGER_URL constant from env var
- api/lab/get_examenes_rips.php: proxy + codigo_legacy mapper
- recepcion.php: banner HTML + consultarExamenesRips/cargarExamenesRips JS
