fix(color): RTC voltage not updating on hw page

Partially revert change in #5031 re:
`enableVBatBridge()` as this needs to be called
reguarly so that the RTC voltage is actually read.
The call to `disableVBatBridge()` while perhaps
technically not needed since `adcRead()` will
clear it itself once the voltage actually read
certainly won't hurt.
