feat: Add Trello configuration fallback and test command

- Add fallback env parsing directly from .env file in config/trello.php
- Fixes issue where cached config prevents env() from reading .env values
- Add artisan trello:test command to diagnose Trello configuration
- Test command checks API credentials, board/list IDs, and connectivity
- Test successfully creates and moves a test Trello card
