LemonMon fb002d1977 fix: stabilize tray item key to prevent position jumps on property changes (#3386)
* fix: keep tray order stable when tooltipTitle changes dynamically

Revert the earlier simplistic key approach: keep getTrayItemKey()
unchanged (id::tooltipTitle) so duplicate-id disambiguation (#1542)
is preserved and persisted id::tooltipTitle entries keep matching.

Instead make persisted-key lookups tolerant of dynamic tooltipTitle:
resolveOrderIndex() in sortByPreferredOrder() does exact match first,
falling back to prefix matching an id::* entry only when the id has a
single instance. findSavedTrayKey()/isTrayIdHidden() replace direct
SessionData.isHiddenTrayId() calls and showTrayId() now receives the
actual saved key.

Prefix fallback is gated by trayItemCountForId() to single-instance
ids only, so multiple items sharing an id always match exactly and
hiding/ordering one never affects the others.

* fix: bail on ambiguous saved tray keys in fallback

* tray: use occurrence index as stable key, add one-time session migration

* tray: pin stable key per item instance so it never flips when siblings come and go

* tray: assign unique per-id sequential keys to avoid collision after sibling exit

* tray: reuse free key slots so a restarted singleton keeps its plain id
