feat(experimental): add interactive messages support (buttons, lists, templates, carousel)

⚠️ EXPERIMENTAL FEATURE - Use only for testing with disposable accounts

Implements full support for WhatsApp interactive messages including:
- Simple text buttons (up to 3 buttons)
- Buttons with images/videos
- List messages (up to 10 items in sections)
- Template buttons (quick reply, URL, call actions)
- Carousel messages (up to 10 scrollable cards)

Features:
- Feature flag 'enableInteractiveMessages' (default: true for dev/testing)
- Prometheus metrics for tracking sends, successes, failures, and latency
- Comprehensive TypeScript types for all interactive message formats
- Extensive logging with warnings about potential account bans
- Automatic 'biz' node injection when feature is enabled

CRITICAL WARNINGS:
- These features may NOT work on non-business WhatsApp accounts
- Can cause temporary or permanent account BANS
- WhatsApp actively blocks this functionality since April 2022
- Messages may be rejected or fail silently
- Use ONLY in dev environment with test accounts

Architecture:
- Added ButtonInfo, Templatable, Listable, Carouselable types to Message.ts
- Extended AnyMediaMessageContent and AnyRegularMessageContent
- Implemented message generation in messages.ts
- Added getButtonType() and getButtonArgs() helpers in messages-send.ts
- Injected 'biz' node in stanza construction with metrics tracking
- Added 4 new Prometheus metrics: interactiveMessagesSent, Success, Failures, Latency

Documentation:
- Complete usage guide in INTERACTIVE_MESSAGES.md
- Examples for all interactive message types
- Metrics monitoring queries
- Troubleshooting guide
- Migration path to WhatsApp Business API
