test: Add unit and integration tests for Telegram bot notification system

[YaronZaki]

Problem Statement

Zero test files exist in quantara/web_app/telegram/. The Telegram bot handles notification delivery for liquidation alerts — critical for user position safety — but has no test coverage for message formatting, notification delivery, or subscription management.

Evidence

• quantara/web_app/telegram/ directory has no test_ files
• No tests for notifications.py, texts.py, markups.py, config.py, __main__.py
• quantara/web_app/tests/ has no Telegram-related test files

Impact

High — untested critical path. Telegram bot failures (missed liquidation alerts, incorrect notifications) go undetected. Users may miss critical position warnings. Notification delivery is a core safety feature for leveraged positions.

Proposed Solution

Add unit tests for: message formatting (texts.py, markups.py), notification delivery logic (notifications.py). Add integration tests for subscription/unsubscription flow with mocked Telegram Bot API.

Acceptance Criteria

• Unit tests cover message formatting functions in texts.py and markups.py
• Unit tests cover notification dispatch logic in notifications.py
• Integration tests cover subscription and unsubscription flow
• Tests mock Telegram Bot API using aioresponses or httpx mock
• All tests pass in CI

File Map

• quantara/web_app/tests/test_telegram.py — New: unit tests
• quantara/web_app/test_integration/test_telegram.py — New: integration tests

Testing Strategy

• Unit: Test texts.py message templates, markups.py keyboard generation, notifications.py send logic with mocked bot
• Integration: Test Telegram webhook handling and user subscription flow

Security Considerations

Ensure tests don't send real Telegram messages. Use mocked bot API.

Definition of Done

• Code implemented and peer-reviewed
• Tests written and passing
• PR linked and merged
