feat: add per-color vector settings and focus adjustment

Add comprehensive PPD options for color-specific vector cutting:
- Focus offset adjustment (-10 to +10 mm)
- Per-color Power, Speed, and Frequency settings for 6 colors:
  Red, Green, Blue, Cyan, Yellow, Magenta
- "Default" option uses global vector settings
- Power 0% skips that color entirely

Update JobOptions to parse new settings from CUPS options and
provide helper methods to look up color-specific settings.
