ipq40xx: whw03v2: change LED color for 'running' state to blue

Change the RGB indicator LED color for the running state from green to
blue. There are various reasons for this change:

- In stock firmware, green means internet connection is up, red means it
  is down, and blue means indeterminate. To track stock behavior as
  closely as possible, OpenWrt should indicate blue by default.

- In the current 23.x OpenWrt releases for this router, the led glows
  blue all the time -not green- because the bootloader sets it blue
  and there is an OpenWrt bug that makes it unable to control the LED.
  The bug is fixed in master, so without this commit there would be an
  unexpected change of behavior for this device in the next release.

- The ports other closely related Linksys devices (such as EA8300 and
  MR8300) get this right and use blue for the running state.
