Include formik and renderExtraValueContent in the memo comparisons
EnvVarRow also omits both props, so it can prevent updated values from reaching EnvVarValueCell. The settings caller changes renderExtraValueContent when environment or collection changes, which can leave SensitiveFieldWarning stale. The delayed append handlers can also use an old formik.values.length when the variable identity does not change. Compare these props at the row boundary, or use stable callbacks with ref-backed length.

fix(bruno-app): resolve typing delay in EnvironmentVariablesTable by memoizing TableRow and row components
Description
This PR fixes input typing lag in
EnvironmentVariablesTable(Environment Variables and Secrets editor).Problem
When typing into input fields (Name, Value, or Description) in
EnvironmentVariablesTable, there is noticeable rendering delay. With larger environment lists, typing becomes significantly slower.bruno.issue.input.environment.variabel.mp4
Root Cause:
TableRow'sReact.memocomparator evaluatedprevProps.children === nextProps.children. BecauseTableVirtuoso'sitemContentgenerates a new JSX element reference on every parent render, children equality always evaluated tofalse. This forced React to re-render all visible rows (30+ rows, 60+ editor instances) on every single keystroke.ErrorMessagewas declared inline insideEnvironmentVariablesTable, creating a new component reference on every render.Fix
TableRowMemoization: Replacedchildrenreference comparison with referential equality check (prevVar === nextVar && prevProps.item?.index === nextProps.item?.index). Typing in a row now skips re-rendering for all other unchanged rows in the table.EnvVarRow&ErrorMessage: MovedEnvVarRowandErrorMessageinto standalone memoized components outside the main render body.handleNameChange,handleNameBlur,handleNameKeyDowninuseCallbackanddisplayedVariablesinuseMemo.computeItemKeyinTableVirtuosoto usevariable.uid.fix.bruno.issue.input.environment.variabel.mp4
