Refactor to apps/ structure

JIGAIDO is now a platform with apps/ as the container.
All telegram-bot files moved to apps/telegram-bot/:
- bot.py, commands.py, cron.py, db.py, schema.sql
- requirements.txt, .env.example, README.md
- Root now holds SPEC.md, README.md, CONTRIBUTING.md only.

Structure:
jigaido/
├── apps/

└── SPEC.md, README.md, CONTRIBUTING.md
