chore: Organize workspace structure - move docs, workflows, scripts to subdirectories

Organization:
- Created docs/ with setup/, guides/, history/ subdirectories
- Created workflows/ with trading/, analytics/, telegram/, archive/ subdirectories
- Created scripts/ with docker/, setup/, testing/ subdirectories
- Created tests/ for TypeScript test files
- Created archive/ for unused reference files

Moved files:
- 17 documentation files → docs/
- 16 workflow JSON files → workflows/
- 10 shell scripts → scripts/
- 4 test files → tests/
- 5 unused files → archive/

Updated:
- README.md with new file structure and documentation paths

Deleted:
- data/ (empty directory)
- screenshots/ (empty directory)

Critical files remain in root:
- telegram_command_bot.py (active bot - used by Dockerfile)
- watch-restart.sh (systemd service dependency)
- All Dockerfiles and docker-compose files
- All environment files

Validation:
 Containers running (trading-bot-v4, telegram-trade-bot, postgres)
 API responding (positions endpoint tested)
 Telegram bot functional (/status command tested)
 All critical files present in root

No code changes - purely organizational.
System continues running without interruption.

Recovery: git revert HEAD or git reset --hard cleanup-before
