Add Python build and packaging configuration

[Copilot]

Repository lacked standardized build configuration and dependency management. Added modern Python packaging setup following PEP 518.

Build Configuration

• requirements.txt - Production dependencies (requests>=2.28.0)
• requirements-dev.txt - Development tooling (pytest, flake8, black, pylint, mypy)
• pyproject.toml - Modern build configuration with package discovery and tool settings
• setup.py - Minimal backwards-compatible shim
• Makefile - Common tasks: install, install-dev, test, lint, format, clean, docker-build

Infrastructure Updates

• .gitignore - Python build artifacts, virtual environments, cache files, IDE files
• Dockerfile - Refactored to use requirements.txt instead of inline pip install
• README.md - Installation, development, and Docker usage instructions

Package can now be installed via pip install -e . or built as wheel with python -m build.

Fix packaged imports before declaring app installable

Packaging app as an installable wheel here produces a broken install: the modules under app/ still rely on repo-root imports such as import config and from Database import Database, so a wheel built from this commit cannot even import app.Trading outside the source checkout. I verified this by extracting the wheel built from pyproject.toml and importing app.Trading, which fails with ModuleNotFoundError; users taking the new package-install path will get an unusable distribution.

Make docker-run pass the trader's required CLI args

This target always runs docker run binance-trader, but trader.py requires --symbol via argparse before it can start. That means the new make docker-run flow exits immediately for every user, even if the image was built correctly and a valid config is present, so the Makefile now advertises a container run path that is nonfunctional out of the box.
