* fix: fix SIE import voucher range bugs from multi-tenant migration and remove describe transaction feature
- Fix reserve_voucher_range RPC parameter mismatch (p_user_id → p_company_id) causing duplicate voucher errors
- Fix create-accounts onConflict from user_id to company_id
- Add reserve-then-adjust pattern: pre-reserve voucher range before batch insert, release unused range on partial failure
- Add release_voucher_range DB function for safe rollback
- Remove DescribeTransactionDialog, describe/batch-describe API routes, and related schemas (feature superseded)

* fix: address Greptile review — voucher range race condition and orphaned entries
- Add p_reserved_highest upper-bound guard to release_voucher_range to prevent
rolling back past numbers claimed by concurrent operations
- Move highestInsertedVoucher tracking to after both headers AND lines succeed,
preventing orphaned journal entries with no lines from being counted as "used"
