Maurice 7266ad99ae Restore nest coverage to >=80% after the #1209 dep bump (istanbul provider + branch tests) (#1213)
* fix(server): set oxc:false in vitest so the SWC transform survives the Vite 8 bump

* fix(server): switch coverage to the istanbul provider (v8 under-reports branches on Vite 8 + Vitest 4)

* test(nest): cover controller/service branches to clear the 80% coverage gate
