## Issue
- Adding `content__non-clickable` everywhere probably isn't the right way when we move forward to separating `all.scss`.
- Not intuitive -- easier to use if it's an attribute to `ClaimPreview`.
## Change
- Consolidate to a re-usable `non-clickable` class.
- Made Wallet Send search preview non-clickable as a temporary band aid until the channel-finder is consolidated.
- `listBlocked`: something is overriding the pointer, so non-clickable isn't working. Removed for now -- doesn't really matter.
- selectMyChannelClaims depends on `byId`, which currently is always invalidated per update, so it is not memoized.
- Most of the use-cases just needs the ID or the length of the array anyways, so avoid generating a Claim array (in selectMyChannelClaims) unnecessarily -- the client need to reduce it back down to IDs again :/
- The simpler boolean also removes the need to memoize the selector, which saves a bit of memory.
