Pon el listado de ingresos al nivel del resto

El listado de ingresos era el unico que seguia volcando la tabla entera sin
filtros, sin totales y sin paginacion: con unos cuantos anos de datos la
pagina se vuelve inmanejable y no hay forma de responder "cuanto ingrese en
marzo".

Se reutiliza lo que ya existe en el listado de gastos en vez de inventar nada:
los mismos filtros de ano, mes y cuenta, el mismo rango de fechas libre con la
misma precedencia y el mismo aviso, la misma paginacion de diez por pagina y
el mismo query_params para que los enlaces de pagina no pierdan los filtros.

Los ingresos marcados como traspaso se siguen listando, porque son movimientos
reales de la cuenta y hay que poder verlos y corregirlos, pero el total los
excluye: de ahi la etiqueta "Total (sin traspasos)".

El estado vacio distingue entre no tener ingresos y que los filtros no
devuelvan nada, para no invitar a crear un ingreso cuando el problema es el
filtro. El colspan de esa fila es 5, que son las columnas de esta tabla.

select_related("account") mantiene el numero de consultas plano: sin el, cada
fila pedia su cuenta por separado.
