fix(deps): pin eslint-plugin-vue to exact version 10.6.2

Error:
- `npm install` fails with "Unexpected top-level property default" error
- ESLint cannot parse configuration from `eslint-plugin-vue` v10.7.0

Reason:
- Version `^10.6.2` allows automatic updates to `10.7.0`
- `eslint-plugin-vue@10.7.0` introduced TypeScript in build process generating `export default`
- This is incompatible with ESLint 8 legacy config format (`.eslintrc.js`)
- Upgrading to ESLint 9 is not viable because `@vue/cli-plugin-eslint` does not support it
- Project uses Vue 2 with vue-cli which requires ESLint 8

Solution:
- Pin exact version `10.6.2` (remove caret) to prevent automatic updates
