Two places map a node id back to its memory card by rebuilding the bare
`memory:<source>:<index>` string: the timeline chart rows and the desktop
starmap's tooltip/body map. With the fingerprint in the id both missed
every card, so a memory row rendered an empty body.
Both now key the card under whichever shapes apply, so an imported or
pre-fingerprint graph keeps working. The CLI help and the memory doc now
describe the id as `journey list` prints it.
