The pure-text RELEVANCE fast path loaded documents via plain findAllById,
which carries no entity graph. With Document.tags LAZY (ADR-022) and no
surrounding transaction, resolveDocumentTagColors hit the dead proxy and
every q-only search (document picker typeaheads) failed with 500
LazyInitializationException. Dedicated findByIdIn declares the same fetch
shape as the other search loaders.
