refactor: sort import statements in src files

[vursen]

Description

The PR sorts import statements in the project with the simple-import-sort ESLint plugin.

The following configuration is used:

"rules": {
  "simple-import-sort/imports": [
    "error",
    {
      "groups": [
        [
          // Side-effects group
          "^\\u0000",
          // External group
          "^",
          // Vaadin group
          "^@vaadin",
          // Parent group
          "^\\.\\.",
          // Sibling group
          "^\\."
        ]
      ]
    }
  ]
}

Depends on #2983
