feat(tools): change base_resolution from dropdown to free numerical input

- Replaced the predefined dropdown list for `base_resolution` in `tools.py` with an open `INT` input (`min`: 128, `max`: 8192, `step`: 8) for the four Resolution Tools.
- Updated `README.md` and `README_EN.md` to reflect the new user interface change.

If you request an extreme aspect ratio that falls below this vital threshold, the node will first scale the resolution up proportionally to protect the generation against melting artifacts, and only then apply strict divisibility.
