fix: lisibilité des textes - blancs/gris illisibles passés en sombre

- Textes blancs sur fond clair (fiches, dialogues, cartes de chat) → couleurs sombres
  - dialogs.less : conteneur roll-dialog-content + labels, options, boutons, valeurs
  - actor.less : inputs/select/textarea des fiches + badges Adaptation/Mutation
  - community.less : info taille, hint, valeur de jauge, niveau de moral
  - vehicle.less : unités ; npc.less : bouton de jet ; items.less : select
- Textes gris des dialogues core Foundry (FilePicker, compendiums, tables, journaux)
  → noirs : suppression des overrides gris theme-dark, texte sombre sur .window-content,
  sidebar sombre conservée en texte clair, messages de tchat en sombre
- CSS : moins/actor/totem.less (ligne influence + bouton en sombre)
