## Issue
Channel links were showing the "This channel isn't staking enough LBRY Credits for link previews." -- channel links shouldn't be showing previews in the first place.
## Change
Moved the logic into `ClaimLink`, which is the better place to put it anyway. I think I was trying to not touch as many components as possible (i.e. not passing `allowPreview` down too many layers) in the initial implementation. This caused the `isChannel` consideration to be missed.
## Issue
- Redo 5636: Disable video previews in comments/posts made by channels below a certain channel staked level
- Closes 5738: expand video preview level requierment to markdown images also
