fix: align OpenClaw tool permission profiles with upstream schema (#1355)

* fix: align OpenClaw tool permission profiles with upstream schema

* fix: remove dead i18n keys and save-blocking validation

- Remove unused `profiles.*` nested i18n keys (dead code, ToolsPanel uses flat `profileMinimal` etc.)
- Remove `invalidProfile` i18n key no longer referenced
- Remove handleSave validation that blocked saving allow/deny when legacy profile exists
- Keep the profile destructuring cleanup from the original PR
