fix(guild): single-pass bucket filter in GuildRepository.SearchAsync

Browse Source 
Replace double-correlated COUNT subqueries in the member-bucket switch
with a project-filter-project pattern that computes the count once per
row.  Add SearchAsync_bucket_2_matches_guilds_with_11_to_25_members to
cover the previously untested medium-bucket range.
