refactor: format SQL queries with multi-line style

Improve readability of SQL queries in db.go by formatting them
with consistent multi-line style. This change affects all database
operations including AddPermanentEntry, DeletePermanentEntry,
AddTempEntry, DeleteTempEntry, and CleanupExpiredTemp.

Also simplifies DeletePermanentEntry and DeleteTempEntry by removing
the RowsAffected() checks - audit logging is now executed unconditionally
regardless of whether rows were actually affected.
