Refactor backend into modular architecture
Split monolithic 631-line app.py into focused modules: **Structure:** - config.py - Configuration and shared state - utils/ - Utility functions (1-2 functions per file) - auth.py - Authentication helpers - docker_client.py - Docker client getter - exec_helpers.py - Command execution helpers - formatters.py - Data formatting utilities - terminal_helpers.py - Terminal operation helpers - diagnostics/docker_env.py - Docker diagnostics - routes/ - HTTP endpoints (1 endpoint per file) - login.py, logout.py, health.py - containers/list.py, exec.py, start.py, stop.py, restart.py, remove.py - handlers/ - WebSocket handlers (1 handler per file) - terminal/connect.py, disconnect.py, start.py, input.py, resize.py, register.py **Improvements:** - Reduced function complexity (from 21 locals to 18 max) - Fixed all pylint import order issues - Removed unused imports (select, timedelta, stat) - Applied lazy logging formatting throughout - Added comprehensive docstrings - Each file has focused responsibility - Easier to test, maintain, and extend **Pylint score improvement:** - Before: 25 problems (15 errors, 10 warnings) - After: Only duplicate code warnings (expected for similar routes) https://claude.ai/code/session_011PzvkCnVrsatoxbY3HbGXz
