chore: modernize dependencies and container runtime (#230)

- requirements: move to Flask 2.x and drop the ancient itsdangerous==0.24 / MarkupSafe<2.1 pins that blocked installs on Python 3.10+; bump redis to 4/5, aiohttp>=3.9, lxml<6, gevent<25; add explicit Werkzeug<3 bound

- Dockerfile: base image python:3.7-alpine (EOL) -> python:3.11-slim so gevent/lxml/aiohttp install from wheels instead of compiling under musl, fixing common build failures and enabling arm64 (e.g. Raspberry Pi)

Refs #167, #183, #192, #178, #149, #158
