fix(api): clean up this slice's own lint violations

Fixed five prettier/prettier formatting errors in the three spec files
Slice 0.10 wrote or edited (world-discovery.service.spec.ts,
local-location-interaction.spec.ts, vertical-slice.seed.spec.ts).
Scoped by hand to just those locations so the pre-existing errors
elsewhere in the workspace, unrelated to this slice, are left alone.

Also corrects the implementation notes, which previously understated
the lint state as entirely pre-existing.
