fix: Light up only the specific pad where tag is placed

- Changed apply_tag_color() to accept pad parameter
- LED effects now apply to tag.pad instead of Pad.ALL
- Tag removal only turns off the specific pad, not all pads
- Added active_pads tracking dictionary
- Added speed parameter support from tag_colors.json
