Sync wishlist re-add: skip wing-it stubs (match the sync), no clickable button

'sami matar' was a wing-it FALLBACK stub — a placeholder the discovery pipeline
makes when it can't resolve a track to real metadata (no album, no cover). The
live sync explicitly skips wing_it_* ids for the wishlist (no metadata to act on),
but my re-add didn't — so it stored a coverless, single-classified placeholder.
That's why: sync didn't add it, no images, marked single.

Fix (parity): reconstruct refuses ids starting 'wing_it_'. Frontend renders the
'-> Wishlist' status as plain, non-clickable text for wing-it rows (with a tooltip)
since they were never actually wishlisted. Real tracks keep the working button +
the byte-identical-payload re-add from the prior fix.
