Subject: [PATCH] fix: brighten ambient light color and increase multiplier for
 room brightness slider

The ambient light color 0x446688 (dark blue-gray) was too dim to produce
visible brightness changes. Changed to 0xccccdd (bright neutral) with 5x
multiplier. Bumped SETTINGS_VERSION to force fresh defaults.
