* Fix multi-term SQLite FTS5 search causing a 500 error
When filtering cards by more than one term, `matching` was called
once per term via an association join. Rails did not deduplicate
association joins, resulting in two JOINs to `search_records_fts`
in a single query. SQLite FTS5 then raised "ambiguous column name"
when evaluating the MATCH condition.
Fix by using a string join instead, which Rails deduplicates so
only one JOIN to `search_records_fts` is generated regardless of
how many terms are searched.
