fix: validate highlightColor before passing to SystemUI

[Wangtaotaoo]

Summary

Fixes a SystemUI crash caused by invalid highlightColor values in theme configurations being passed directly to Color.parseColor() in HyperOS's DynamicIsland.

Problem

When a theme (imported .hbr file or legacy config) contains an invalid highlight_color value (e.g. "013" without # prefix), resolveColor() returns it as-is. SystemUI's DynamicIslandBaseContentView.updateDarkLightMode() then calls highlightColor.toColorInt(), which throws:

FATAL EXCEPTION: main
Process: com.android.systemui
java.lang.IllegalArgumentException: Unknown color
    at android.graphics.Color.parseColor(Color.java:1402)
    at miui.systemui.dynamicisland.window.content.DynamicIslandBaseContentView.updateDarkLightMode

This crash only triggers when:

• The island region background is dark (isLight = false)
• The island is in BigIsland state (not Expanded)
• highlightColor is non-empty but unparseable

Fix

Added toSafeColorHex() validation at all return paths of resolveColor() in BaseTranslator. If Color.parseColor() throws IllegalArgumentException, it falls back to the provided default hex value and logs a warning.

What was tested

• Injected a theme with "highlight_color": "013" (the exact value from the original bugreport)
• Sent notifications with dark wallpaper active
• Confirmed SystemUI no longer crashes
• Confirmed logcat shows: W/BaseTranslator: Invalid highlight color "013", falling back to "#FFFFFF"

[Wangtaotaoo]

It's still unclear how highlight_color ended up with an invalid value ("013").
I couldn't find the root cause of the config corruption.
However, from the user's bugreport log, it's confirmed that SystemUI crashed because HyperBridge passed this invalid value to the DynamicIsland.
