update Colors for network switch stickers for readability

[Starshine]

Readability

Last year we had automagically generated stickers but the BG colors were found to be too dark for adequate contrast. Team was concerned we shouldn't make them too light either, or we'd have to squint to be sure which type of port it was.

Adequate colors were found and tuned manually in GIMP.

Merge these values into the label generator:

Uplink

(hot green) 00d900

Downlink

(ochre yellow) d9d900

Unused

(mid/lt grey) bfbfbf

AP

(hot teal) 00d9d9

VLANs by name

(lavender) bfbfff

Mass Flash

(DH magenta) d900d9

Names in parentheses are for human reference only, to catch if any typo leads to a color of another hue.

Acceptance Criteria

The stickers generated from the map of the true network shall be as readable as the final stickers from SCaLE 21x.
