The client registry derived display names from a hardcoded map of
"well-known" MCP clients (claude-desktop, claude-ai, continue-dev,
zed-editor, vscode-mcp). This baked a recognized-client list into the
server even though admission already requires explicit opt-in via
ALLOWED_MCP_CLIENTS (fail-closed when unset).
Mirror the management-API surface (ALLOWED_MGMT_CLIENT), which has no
built-in client list: remove the map and derive the display name
generically from the client_id. Default remains none; clients must be
added explicitly and DCR stays off unless ENABLE_DCR=true.

Both auth surfaces now fail-closed by default:
- ALLOWED_MCP_CLIENTS: removed the silent `claude-desktop` and
`test-mcp-client` fallbacks. Empty/unset env var leaves the registry
empty so /oauth/authorize rejects every client_id.
- ALLOWED_MGMT_CLIENT (new): comma-separated list of OIDC client_ids
whose tokens are accepted by /api/management/*. Enforced in
verify_token_for_management_api on both the cache-hit and cache-miss
paths against the token's client_id claim. Unset/empty rejects all.
Compose: set ALLOWED_MGMT_CLIENT=nextcloudMcpServerUIPublicClient on
mcp-multi-user-basic so the existing Astrolabe integration test
(test_astrolabe_chunk_context.py) still passes.
env.sample documents both vars and notes they may be consolidated later.

- Document wildcard scope policy in ClientRegistry class docstring
- Add hostname None guard and IPv6 loopback (::1) to redirect URI validation
- Simplify redirect URI scheme validation into single guard clause
- Add try/finally cleanup to DCR client deletion test
- Validate 302 Location header in unknown client rejection test
- Add unit tests for IPv6 loopback, malformed URIs, and DCR proxy paths

Remove the unused ALLOWED_MCP_CLOUD_CLIENTS env var — all clients are
defined via ALLOWED_MCP_CLIENTS or the static well-known defaults.
Add keycloak as an integration test profile in CI now that login-flow
replaces the old bearer token approach for external IdPs.

Merge ALLOWED_MCP_CLOUD_CLIENTS into a single ALLOWED_MCP_CLIENTS env var
that supports both simple client IDs and pipe-separated client_id|redirect_uri
entries. Enforce HTTPS for non-localhost redirect URIs, warn on malformed
entries, and use wildcard scopes for all static clients (upstream IdP enforces
actual scopes). Add deprecation warning for the old env var.
Also fixes DCR proxy error messages to reference only ALLOWED_MCP_CLIENTS and
use "Upstream" instead of "Nextcloud" for IdP-agnostic language. Enables
Login Flow v2 + DCR on the mcp-keycloak docker-compose service.
Adds 17 unit tests for ClientRegistry parsing/validation and 7 keycloak
integration tests for DCR lifecycle, AS metadata, and client authorization.
