Fix build errors and prepare for deployment

- Fix const reassignment in Phase 2 reports export (use let for mutable vars)
- Fix TypeScript interface to match Prisma reconciliation schema
- Fix array comparison logic in bank CSV parsing
- Temporarily disable pdf-parse due to module compatibility issue (pre-existing)

All phases now build successfully with zero errors.
