feat(issues): tipo/categoría de incidencia (defecto/seguridad/calidad/documentación/otro)

- Issue::TYPES + typeLabels() (ES) + accessors type_label/type_color; columna type
  (string, default 'other') + fillable.
- IssueForm: select "Tipo de incidencia" con validación/carga/guardado.
- IssueTable: columna Tipo (badge) + SelectFilter por tipo.
- IssueDetail: badge de tipo en la cabecera.
- Sync offline: issue.create/update aceptan type; bundle (mapIssue) lo incluye.

Tests: IssuesEnhancementsTest (create muestra el campo vía HTTP, edición persiste) +
MobileApiTest (create con type). Suite 61 passing (solo 2 pre-existentes sqlite).
