feat: implement Telegram API integration and fix TEE memory usage (#71)

* fix: add --disable-wasm-trap-handler flag to resolve memory range error

* fix: increase heap memory allocation to 7GB to resolve memory range errors

* feat: implement Telegram API integration using fetch

- Replace mock implementation with actual Telegram Bot API calls
- Use Node.js fetch to send messages via https://api.telegram.org/bot
- Add proper error handling for API responses
- Include detailed error messages in response
- Fix linter issues with property shorthand

* test: update test expectations for new Telegram API response format

- Update e2e tests to handle new response structure with result field
- Fix test expectations for error status codes (404 instead of 500)
- Update unit tests to use fetch mocks instead of node-telegram-bot-api
- All 45 tests now passing with real Telegram API integration
