v0.0.27: TG-compatible bots — plaintext send, numeric IDs, webhooks, BotFather

Bot compatibility:
- Clients send plaintext bot_message to bot aliases (no E2E encryption)
- Numeric chat_id: fp_to_numeric_id() deterministic hash, accept string/number
- Webhook delivery: POST updates to bot's webhook URL (async, fire-and-forget)
- getUpdates timeout raised to 50s (was 30, TG uses 50)
- parse_mode HTML rendered in web client
- E2E bot registration: optional seed + bundle for encrypted bot sessions

BotFather + instance control:
- --enable-bots CLI flag (default: disabled)
- BotFather auto-created on first start (@botfather alias)
- Bot ownership: owner fingerprint stored in bot_info
- All bot endpoints return 403 when disabled

Bot Bridge:
- tools/bot-bridge.py: TG-compatible proxy for unmodified TG bots
- Translates chat_id int↔string, proxies getUpdates/sendMessage
- README with python-telegram-bot and Telegraf examples

Test fixes:
- Updated tests for ETH address display in header/messages
