Refactor: Fix untyped array in MessageBox

[Refactor] Fix untyped array in MessageBox.tsx:76

Description

In apps/meteor/client/views/room/composer/messageBox/MessageBox.tsx at line 76, there is a generic untyped array (any[]). This practice leads to type inference failure when the array is passed as a prop, causing a loss of type safety and information throughout the component.

Bug / Issue Details

• Rocket.Chat version: Latest / Develop
• Target File: apps/meteor/client/views/room/composer/messageBox/MessageBox.tsx (lines 76-77)

Expected behavior

The code should use strict typing to ensure that the IDE and the TypeScript compiler can correctly infer types, avoiding the "leakage" of any into other parts of the frontend.

Actual behavior

The current implementation uses a shortcut that bypasses linting but compromises type safety:

const a: any[] = [];
const getEmptyArray = () => a;

Proposed Solution

Replace the untyped array with a strictly typed empty array or a typed function return.

const getEmptyArray = (): never[] => [];

Start in apps/meteor/client/views/room/composer/messageBox/MessageBox.tsx at lines 76-77 and inspect how getEmptyArray is passed as a prop. Replace the untyped array with an explicit type, then run the relevant frontend TypeScript and lint checks. Done means the any[] usage is removed without type errors or loss of type safety.
