fix/tooltip-facet-positioning conflicted with main in two example files where both sides modified the same Map.get() spread lines differently — the branch dropped ?? {}, while main replaced it with as object.

Changes

• shift-map.svelte — adopt main's as object cast over the branch's bare spread
• spike-map.svelte — same resolution

<!-- before (branch) -->
...electionByFips.get(Number(feat.id))

<!-- after (resolved) -->
...(electionByFips.get(Number(feat.id)) as object)
