fix(search): set gin_fuzzy_search_limit only for search queries

Browse source 
The limit was a connection parameter, so it applied to every GIN index
scan, not only full-text search: recipient lookups and Oban job queries
could return incomplete, random results. Set it with SET LOCAL around
the search query only, configurable under Pleroma.Search.DatabaseSearch.

The default stays 500 for search: measured on a 74M-object database,
higher limits or none make searches for common words exceed the query
timeout. Remote fetches for URL queries run outside the transaction.

Based on Akkoma 811f0a468.

gin_fuzzy_search_limit is now only set for search queries (configurable under Pleroma.Search.DatabaseSearch), so other GIN index scans such as recipient lookups and Oban job queries are exact again
