fix: Skip missing tenant schemas in demo user seeding

SeedDemoUsers iterates all tenants from DEMO_OPERATOR_TENANT (comma-
separated). When a listed tenant has not been provisioned in the
current environment (e.g. payg_energy on demo), the schema lookup
fails with ErrTenantSchemaNotProvisioned and aborts the entire
seeding operation - even though earlier tenants (volterra_energy)
were seeded successfully.

Skip tenants with missing schemas instead of failing. Log a warning
so the skip is visible in deploy logs without blocking the pipeline.
