Fix two issues preventing OAuth tests from passing:
1. Set oidc_client_id and oidc_client_secret on Settings object
- These were being read from environment but not propagated to the
UnifiedTokenVerifier settings instance
2. Use client_issuer instead of issuer for JWT validation
- client_issuer accounts for NEXTCLOUD_PUBLIC_ISSUER_URL override
- Fixes "Invalid issuer" errors when public URL differs from internal
3. Accept resource URL with /mcp path in audience validation
- During DCR, resource_url is registered as "{mcp_server_url}/mcp"
- Tokens correctly include this full path as audience
- Verifier now accepts both "http://localhost:8001" and
"http://localhost:8001/mcp" as valid MCP audiences
These changes restore OAuth functionality while maintaining ADR-005
security requirements for proper audience validation.
