The AI chat assistant scoped tool queries by company but ignored the per-user Bouncer abilities the rest of the app enforces, so any `use ai` holder could read customers, invoices, payments, and company financials their role couldn't otherwise see. Each AiTool now declares a required ability (entity-aligned); the registry hides unauthorized tools from the model and refuses to execute them as a backstop. Separately, admin/owner-supplied URLs were fetched server-side with no guard against private/reserved targets (SSRF): the AI base URL, the CurrencyConverter "DEDICATED" exchange-rate URL, and S3/Spaces file-disk endpoints. A shared PrivateNetworkGuard now backs a PublicHttpUrl validation rule (save-time) and runtime guards in each driver. - AiTool::requiredAbility() + mapping across all 12 tools - AiToolRegistry filters schemas() by ability and re-checks in execute() - PrivateNetworkGuard / BlockedUrlException / PublicHttpUrl rule (new) - Rule wired into AI config (service + 3 controllers), exchange-rate, and file-disk endpoints; runtime guards in OpenRouterDriver, CurrencyConverterDriver, and FileDiskService - Tests for ability filtering, the guard, the rule, and 422 rejections
