Fix lint errors and suppress generated-bundle lint noise

[aliamerj]

Motivation

• Resolve lint-blocking issues reported by eslint so lint exits successfully without introducing behavior changes.
• Reduce thousands of non-actionable warnings coming from a generated bundle so real issues are easier to spot.

Description

• Move global comment scroll handler into a useEffect with cleanup to satisfy immutability rules in components/FeatureDetail/CommentsContainer.tsx.
• Remove unnecessary mount-state effect from components/FromatDistanceToNow/FormatDistanceToNow.tsx so we avoid set-state-in-effect warnings while preserving output.
• Replace a manual memoized callback with a direct lookup for author role in components/RenderComment/RenderComment.tsx to avoid React Compiler memoization warnings.
• Fix useMemo dependency list by adding projectId in components/WidgetPreview/WidgetPreview.tsx.
• Simplify PaymentContext to provide paddlePay inline and remove problematic memoization assumptions in contexts/PaymentContext.tsx.
• Convert getUserRole to a stable useCallback and update dependent callbacks in contexts/ProjectPermissionProvider.tsx.
• Update tailwind.config.js to use an ESM import for typography and export a named config object to satisfy lint rules.
• Ignore the generated bundle public/packages/widget.iife.js in eslint.config.mjs to eliminate thousands of non-actionable warnings.

Testing

• Ran npm run lint after the changes and the command now completes successfully with 0 errors and only non-blocking warnings (lint exit code 0).
• No other automated tests were modified or required for these changes.
