webdav encode_uri_path runs on every PROPFIND href and did
.map(...).collect::<Vec<_>>().join("/"), allocating a String per segment plus
a joined Vec. Write each utf8_percent_encode Display adapter straight into a
single preallocated String. Behavior is identical (split on '/', encode each
segment, join with '/'), including leading/trailing-slash edge cases.
subject_group list / list_with_counts each issued a second SELECT COUNT(*)
round-trip for the total. Fold it into the page query via COUNT(*) OVER() —
the pattern folder_db_repository already uses — halving the round-trips.
total_count is read from the first row and is 0 on an empty page, matching
folder_db_repository's documented convention.
