DEV: Track SQL queries from MiniSql (#28824) 
`track_sql_queries` only returned queries that were executed by
ActiveRecord. All queries executed through DB.exec, DB.query and others
were not returned.

PERF: Preload voters_count and has_voted (#28808) 
These fields are often used when serializing topics which may contain
multiple polls. On average, serializing a poll took 2+N queries where N
is the number of options. This change reduces the number of queries to
3, one for each field (Poll#voters_count, PollOption#voters_count and
Poll#has_voted?).
