fix: correct engine column names, dashboard revenue calc, email config, and UX issues

- Fix buildLineInserts() using wrong DB column names (cost_center_id → cost_center,
  project_id → project) and add missing tax_code field
- Replace transaction-based dashboard income/expense with journal-entry-based
  calculation using account classes (3xxx revenue, 4-7xxx expenses)
- Add email/phone fields to CompanySettings type, validate RESEND_FROM_EMAIL
  in isResendConfigured(), remove unsafe type casts in invoice send/reminders
- Always auto-fill line description from account name in JournalEntryForm
- Reorder expense lines in TransactionBookingDialog so 1930 is always first row
