Tor support, use SeleniumBase instead of DrissionPage (#123)

Refactor: Improve Docker build, add Tor support, use SeleniumBase

- Overhauled Dockerfile:
    - Switched to python:3.10-slim base.
    - Implemented multi-stage builds (base, standard, tor).
    - Consolidated RUN layers for efficiency.
    - Added locale/timezone setup.
- Added Tor setup and iptables configuration in dedicated stage/script.
- Replaced DrissionPage with SeleniumBase for Cloudflare bypassing.
- Added Tor support via `docker-compose.tor.yml` and `tor.sh` script.
- Updated `docker-compose.yml` to build locally and changed default port
to 8083.
- Added `docker-compose.dev.yml` and `docker-compose.tor.dev.yml`.
- Updated `entrypoint.sh` for timezone and sudo usage.
- Added/Updated environment variables (`TZ`, `USING_TOR`, etc.).
- Improved `.dockerignore`.
- Updated `readme.md` to reflect port changes, build process, document
`TZ`, and add details about the new Tor variant.
