fix(cli): dedupe import resolutions before ApplyAsync

Browse Source 
PreviewAsync can emit multiple ImportPreviewItem rows for the same
(EntityType, Name) -- one per modified member of a template, for
example. ApplyAsync internally calls .ToDictionary() on the
resolutions list and throws ArgumentException on duplicate keys.

The Central UI's BuildDefaultResolutions already dedupes via a
dictionary assignment (last-write-wins). Mirror that in the CLI
handler so 'bundle import' tolerates the duplicate-rows shape the
preview returns.
