refactor(collections): rule evaluators take the real row; both 45-field converter twins deleted

checkRulesAgainstBook/evaluateRule and the service's EvaluateRules
existed in two parallel universes: one over database.MediaItems (what
every query actually returns) and one over ListMediaItemsRow (what two
hand-written 45-field mediaItemsToListMediaItemsRow converters
produced — verbatim twins in the handler and the dashboard service,
with a URL-resolution side effect baked into a "converter"). The rule
fields (genre/series/author/language/publisher/copyright_year/tags)
all exist on MediaItems, so the evaluators now take the real row and
the converters, their three call-site loops, and the dead
ApplyAutoAssignRules entry point (zero callers) are gone.

The rules surface is wire-covered by the collections rules scenarios;
handlers+services suites and the full pin/H1/H3 battery green.
