Migra formularios de gastos/ingresos/cuentas/etc al parcial comun

Sustituye {{ form.as_p }} (o el bucle for field in form repetido a
mano en expense_form.html) por {% include "expenses/_form_fields.html" %}
y anade class="app-form" al <form> en:

  - categories/form.html, categories/list.html (alta de categoria)
  - expenses/account_form.html
  - expenses/expense_form.html
  - expenses/income_form.html
  - expenses/tag_form.html
  - fuel/create.html
  - goals/form.html
  - registration/login.html

De paso:
- categories/list.html: se corrige indentacion de la tabla y las
  etiquetas <a> de "Editar"/"Eliminar" (estaban dentro de una celda
  sin problema funcional, solo desalineadas) y se anade una <th> vacia
  para la columna de acciones.
- goals/form.html: el bloque title y el <h1> tenian "Nuevo objetivo"
  fijo aunque la vista goal_edit ya pasa title="Editar objetivo" en el
  contexto; ahora la plantilla usa {{ title }}, asi que el formulario
  de edicion deja de decir "Nuevo objetivo" por error.

No se toca la logica de las vistas ni los formularios en forms.py.
