refactor(frontend,plugins): normalise les DTOs review backend et corrige le mock (#120)

- plugin.ts: normalizeReview() garantit issues/installable définis même si backend omet ces champs
- mock/index.ts: MockPluginGateway.uninstall() retourne removalOutcome pour cohérence avec le domaine
- domain/index.ts: PluginUninstallResult ajoute removalOutcome optionnel
