FINERACT-2530: Fix 500 error on GET /provisioningentries/{id} when no loan products exist

[shubhamkumar9199]

Change INNER JOIN to LEFT JOIN in PROVISIONING_ENTRY_SUM_RESERVED_SCHEMA so that provisioning entries with no associated loan product rows still return a valid result instead of throwing EmptyResultDataAccessException.
