Use singular in full-service path

[palday]

Legolas schema use singular by convention and Onda follows this convention.

I'm unsure whether this should be considered a breaking change and hence what the necessary version bump is. In some sense it's a bug fix, but it definitely changes behavior in a non compatible way.

i'd consider it breaking (and thus entail a major bump) even though it's a bugfix since the likelihood of downstream users/code hardcoding these extensions is pretty high

given that it's a breaking change anyway I think I'd be a fan of just removing the magical extension handling bits altogether and changing the interface from e.g. signal_prefix to signal_file_path

better to just let the caller fully choose their own file paths/names IMO

I do think that for the "full service" option it's good to have defaults, but yeah let's make them file names instead of prefixes (if we're making a breaking change anyway)
