refactor: telegram + portfolio in-process (drop shared MCP)

Each bot now manages its own notification + portfolio aggregation:

* TelegramClient calls the public Bot API directly via httpx, reading
  CERBERO_BITE_TELEGRAM_BOT_TOKEN / CERBERO_BITE_TELEGRAM_CHAT_ID from
  env. No credentials → silent disabled mode.
* PortfolioClient composes DeribitClient + HyperliquidClient + the new
  MacroClient.get_asset_price/eur_usd_rate to expose equity (EUR) and
  per-asset exposure as the bot's own slice (no cross-bot view).
* mcp-telegram and mcp-portfolio removed from MCP_SERVICES / McpEndpoints
  and the cerbero-bite ping CLI; health_check no longer probes portfolio.

Docs (02/04/06/07) and docker-compose updated to reflect the new
architecture.

353/353 tests pass; ruff clean; mypy src clean.
