feat(cli): show bare station/episode id as its own column in station find

`station find` previously surfaced the id only inside the Location href
(e.g. /v1/playback/station/s228737). Render the bare id (s228737,
p1864248, or radiobrowser UUID) alone in a leading column so it is easy
to copy-paste, with the name beside it and the description plus full
Location indented below. The Location line stays because that path, not
the bare id, is what play/preset commands consume.
