Add Custom Preview Component for Telegram Provider

[nevo-david]

Overview

The Telegram provider currently uses the default GeneralPreviewComponent instead of a platform-specific preview that matches Telegram's UI/UX.

Current State

• Provider file: apps/frontend/src/components/launches/providers/telegram/telegram.provider.tsx
• Using: withProvider(null, undefined, ...) - no custom preview component
• Falls back to: GeneralPreviewComponent

Needed Implementation

Create a TelegramPreview component that:

• Matches Telegram's message design (clean messenger layout with blue accents)
• Shows proper chat bubble interface
• Displays channel/group context with proper formatting
• Shows Telegram-specific elements like views, reactions, forwards
• Includes Telegram's distinctive blue theme and typography
• Handles different message types (text, media, stickers)
• Shows proper timestamp and delivery status

Reference

See existing implementations:

• apps/frontend/src/components/launches/providers/medium/medium.provider.tsx (MediumPreview)
• apps/frontend/src/components/launches/providers/devto/devto.provider.tsx (DevtoPreview)

Technical Details

• Component should be added as second parameter in withProvider(null, TelegramPreview, ...)
• Should implement FC<{ maximumCharacters?: number }> interface
• Use useIntegration() hook to access post content and settings

Priority

Medium - Telegram is a major messaging platform with broadcasting features
