refactor: remove dead code via Rector

rector.php gets the deadCode set: @param/@return/@var tags that only
repeat native types, === true comparisons, three unused constructor
dependencies (DateService, ProductDataService, AjaxWatchlistController),
the unused reseller lookup in ContextProcessor and an always-false check
in AbstractMappedFinisher (trimExplode with removeEmpty never yields an
empty remote name).

Checked locally: frontend crawl (~1,900 URLs) and the backchannel APIs
render the same as before.
