Describe the Bug

The file app/lib/methods/helpers/helpers.ts has @ts-nocheck at the top, which disables TypeScript checking for the entire file. All 8 exported functions lack proper TypeScript type annotations, reducing type safety and developer experience.

Steps to Reproduce

1. Open app/lib/methods/helpers/helpers.ts
2. Observe @ts-nocheck - TEMP comment at line 1
3. Notice all function parameters lack type annotations (e.g., room, sender, item are untyped)
4. Run yarn lint or TypeScript compiler - no type errors are reported for this file despite missing types

Expected Behavior

• Remove @ts-nocheck directive
• Add proper TypeScript types to all function parameters and return types
• All functions should have complete type annotations
• TypeScript compiler should properly check this file

Actual Behavior

• TypeScript checking is disabled for the entire file
• No type safety for 8 exported functions
• Potential runtime errors that could be caught at compile time
• Poor IDE autocomplete and IntelliSense support

Additional Context

File: app/lib/methods/helpers/helpers.ts

Functions to migrate:

• isGroupChat(room)
• getRoomAvatar(room)
• getUidDirectMessage(room)
• getRoomTitle(room)
• getSenderName(sender)
• canAutoTranslate()
• isRead(item)
• hasRole(role)
• hasPermission(permissions, rid?)

Impact: This file is used in multiple places:

• app/lib/hooks/useUserData.ts
• app/containers/MessageComposer/components/ComposerInput.tsx
• And potentially other files
