Fix ESLint config for eslint-plugin-react-hooks 7.0.1

[Copilot]

The plugin:react-hooks/recommended-legacy preset was removed in eslint-plugin-react-hooks 7.0.1, breaking the lint command.

Changes

• Removed deprecated plugin:react-hooks/recommended-legacy from extends
• Added react-hooks to plugins array
• Manually configured core hooks rules to maintain v6 behavior:

  rules: {
    "react-hooks/rules-of-hooks": "error",
    "react-hooks/exhaustive-deps": "warn",
  }

The v7 recommended preset now includes 17 React Compiler rules that would flag 30+ violations across the codebase. This approach preserves existing behavior while fixing the immediate breakage.
