Disable react/prop-types project-wide; drop dead PropTypes from TogglePanel

React 19 removed runtime propTypes validation. The rule still ships
in plugin:react/recommended (jsx-eslint/eslint-plugin-react#3753
tracks removing it) but no longer reflects this codebase's reality.

- .eslintrc: set react/prop-types: 0 with rationale pointing at the
  upstream issue.
- ServerComponentsPage / LiveActivity / CommentsFeed: drop the per-file
  `/* eslint-disable react/prop-types */` workarounds from 7b9093e;
  the rule is now off everywhere.
- TogglePanel: drop the prop-types import and the `TogglePanel.propTypes`
  declaration we introduced; React 19 doesn't validate them.

Existing components elsewhere with their own PropTypes are unaffected —
the rule only ever required declarations, never validated; disabling
just stops the requirement.
