fix(sidebar): reorder sidebar nav items by id to stop drag drift (#1206)

* fix(sidebar): reorder nav items by id instead of positional index

The Settings sidebar customizer rendered library rows with one filter and
reordered them with another, so a hidden/gated item (luckyMix when AudioMuse
is unavailable) made the rendered list shorter than the reorder list and drag
indices landed one slot off — rows jumped back on drop. Replace the index-based
reorder with an id-based primitive shared by the customizer and the in-sidebar
long-press DnD, so a render filter can no longer desync the move. Unknown,
cross-section, conserved, or no-op drops are rejected.

* docs(changelog): note sidebar reorder fix (#1206)
