hasFielConfigured() now checks both:
1. Legacy mode: fiel_credentials in central DB (Horux 360)
2. Despacho mode: fiel_contribuyente in tenant DB
This fixes the SAT daily sync omitting despacho tenants that have
FIEL loaded per-contribuyente but not in the central fiel_credentials table.
- Daily sync already covers all active tenants with FIEL (no plan filter)
- Incremental sync now runs for all plans EXCEPT:
- 'custom'
- 'mi_empresa'
- 'mi_empresa_plus'
- Renamed getEnterpriseTenantsWithFiel -> getIncrementalTenantsWithFiel
- Updated logs to reflect new eligibility
- Add Conceptos tab in CFDI page with column filters, sorting, pagination
- Add GET /cfdi/conceptos endpoint with filters and orderBy
- Backfill cfdi_conceptos from legacy XMLs (824k concepts inserted)
- Fix CFDI delete button (bypass subscription check, add alerts)
- Fix export to Excel (fetch all filtered results, limit 10k)
- Fix facturacion page concepto delete bug (immutable updates, unique ids)
- Add Facturapi live key auto-generation and caching
- Fix SAT fechaPagoP parsing
- Add metrics cache support for current year
- Increase DB pool max to 15
- login(): check platformRoles before membership validation; fallback to first active tenant for superset admins
- refreshTokens(): allow refresh for superset admins even without memberships
- tenantMiddleware: skip tenantPool resolution when tenantId is empty for superset admins
- Add metabase.service.ts for automatic DB registration
- Hook createTenant, addTenantToOwner and deleteTenant to sync with Metabase
- Keep all existing features from latest version
