Deduplicate the new like-result acceptance steps behind one render helper,
and extract the bch.loping.net transaction link shared by the New Post result
modal, the post options menu, and the like/tip result into a block-explorer
service. Cover the LikeTipPage open/parse/handler failure branches and add
property tests for the explorer URL, the LikeResult markup, and the result
modal state machine.
CRAP is at or below 5 with full coverage on the changed services; every
changed/new plain source file scans at 21 or fewer mutation sites. The
existing mutation manifests are left for the mutation tool to refresh.
