fix: resolve merge regressions and Prisma type gaps in transactions/auth services (#891)

- Restore two try blocks left without catch handlers after merging main

  (transactions.service.ts: recordOnBlockchain, verifyOnBlockchain)

- Remove duplicate/conflicting 'updated' declaration in update()

- Restore transaction-not-found check dropped from update() during the merge

- Restore nextCursor/previousCursor pagination fields dropped from findAll()

  during the merge

- Fix TypeScript errors from Prisma client not re-exporting model types

  and enums under the Prisma namespace in this generator version

  (Transaction, TransactionTaxStrategy, TransactionType, TransactionStatus

  in transactions.service.ts; BlacklistedToken, Document, ApiKey,

  PasswordHistory in auth.service.ts)

- Add explicit guard rejecting TransactionStatusDto.FAILED, which has no

  corresponding value in the Prisma schema's TransactionStatus enum

- Use existing this.toNumber() helper for Decimal conversion instead of

  calling .toNumber() directly, matching the pattern already used in

  getAnalytics()

- Normalize nullable Prisma fields (blockchainHash, contractAddress,

  notes) to undefined to match TransactionResponseDto's optional fields

- Remove remaining 'as any' cast in findAll()'s cursor construction

- Fix misplaced docstring on updateEscrow() and restore its unused-param

  lint suppression
