Ajoute des tests unitaires JUnit 5 (CP9 - plans de tests)

14 tests couvrant VoteConfig (Spigot + Velocity) et YamlPendingVoteStore
(Spigot + Velocity) : valeurs par defaut, portee per-server/global,
merge de config sans ecraser l'existant, incrementation/reset des
votes en attente, colorisation des messages.

Mockito pour VoteConfig/YamlPendingVoteStore cote Spigot (mock de
VoteNetworkSpigot, pas besoin de serveur Bukkit reel). Cote Velocity,
tests directs sans framework (classes deja decouplees de Velocity-API).
