Add automatic import sorting with eslint-plugin-simple-import-sort

[Copilot]

Enforce alphabetical ordering of import statements across the codebase using ESLint.

Changes

• Added eslint-plugin-simple-import-sort to dev dependencies
• Configured simple-import-sort/imports and simple-import-sort/exports rules in eslint.config.mjs
• Applied automatic sorting to 130+ files using eslint --fix

Behavior

The plugin groups and sorts imports as follows:

// External packages, sorted alphabetically
import alertifyjs from 'alertifyjs'
import debounce from 'debounce'
import throttle from 'throttleit'

// Blank line separator

// Local imports, sorted alphabetically
import ContextMenu from '../control/ContextMenu'
import ToolBar from '../control/ToolBar'
import forwardMethods from '../forwardMethods'

Import order violations are now caught by ESLint and auto-fixable with --fix.
