[csl] use mPanChannel as default CSL channel (#11336)

Browse Source 
This commit updates the CSL channel selection logic. When a CSL
channel is not explicitly set, the code now uses the tracked
`mPanChannel` (the current Thread PAN channel) instead of
`mRadioChannel` (the current channel the radio is listening on). This
ensures that the CSL channel aligns with the Thread PAN channel, even
when the radio temporarily switches to other channels, such as during
an MLE discover scan.
