Add the ITCC Overview, a Teiler without OIDC, to the itcc project

Enabled with ENABLE_TEILER, served under /itcc-overview. Local apps:
quality report, export, validator (ENABLE_OMICS) and local explorer
(ENABLE_LENS). Central apps: explorer and data warehouse. The dashboard
lists apps only if local and central apps exist.

teiler-backend:develop, because 1.0.2 (latest) rejects the relative
orchestrator URL.
