Fix continuous injection of lasers (#4112)

* Fix continuous injection of lasers

- define new member functions nLasers and nContainers;
- loop over all containers, not just over all "species".

* Fix update of injection position for lasers

* Fix CodeQL issues

* Fix style

* Rename `ispecies` as `index`

* Rename functions to update injection and antenna positions
