fix: hide empty-state copy on queue credential fail-closed (Closes #458)

When fetch_error is set, render only the unavailable banner and an
explicit not-fetched inventory note. Suppress queue tables, pagination
proof, and "No open items." copy that implied a successful empty fetch.

+# Internal web UI — local development (#426)
+
+Read-only MVP skeleton for the MCP Control Plane operator console. Gitea,
+MCP capability gates, and `skills/llm-project-workflow/` remain the source of
+truth; this UI only provides route stubs and layout.
+
+## Prerequisites
+
+- Python 3.11+ with project dependencies installed (`pip install -r requirements.txt`)
+- No secrets in repo, config, or client bundle
+
+## Start the server
+
+From the repository root (or an issue worktree):
+
+```bash
+./scripts/run-webui
+```
+
+Or directly:
+
+```bash
+python3 -m webui
+```
+
+Optional environment variables:
+
+| Variable | Default | Purpose |
+|----------|---------|---------|
+| `WEBUI_HOST` | `127.0.0.1` | Bind address (keep local for MVP) |
+| `WEBUI_PORT` | `8765` | Listen port |
+
+## Routes (MVP)
+
+| Path | Description |
+|------|-------------|
+| `/` | Home / operator overview |
+| `/health` | JSON liveness (`status`, `service`, `mode`, `timestamp`) |
+| `/queue` | Live PR and issue queue dashboard (#429) |
+| `/api/queue` | JSON queue export with pagination metadata |
+| `/projects` | Project registry list (#427) |
+| `/projects/{id}` | Project detail + onboarding checklist |
+| `/api/projects` | JSON registry export |
+| `/prompts` | Prompt library with per-prompt copy buttons (#428) |
+| `/api/prompts` | JSON prompt export with workflow hashes |
+| `/runtime` | Stub — MCP runtime health (#430) |
+| `/audit` | Stub — report audit paste (#431) |
+| `/worktrees` | Stub — hygiene dashboard (#432) |
+| `/leases` | Stub — lease visibility (#433) |
+
+All routes are GET-only. POST/PUT/PATCH/DELETE return `405` with
+`read-only-mvp`.
+
+## Project registry (#427)
+
+Versioned registry file: `webui/data/projects.registry.json` (schema version `1`).
+
+Override path with `WEBUI_PROJECT_REGISTRY` when operators keep a machine-local
+copy outside git. The registry stores repo identity, remotes, profile names,
+workflow/schema path references, and onboarding checklist steps — never tokens
+or credentials.
+
+Seed entry: **Gitea-Tools** on `https://gitea.prgs.cc` with `prgs-author`,
+`prgs-reviewer`, and `prgs-reconciler` profiles.
+
+## Prompt library (#428)
+
+Prompts are generated at load time from canonical workflow files under
+`skills/llm-project-workflow/workflows/`. SHA-256 hashes are computed from
+`WEBUI_REPO_ROOT` (defaults to the repository root). Prompt bodies are short
+copy/paste starters; canonical workflow files remain the only full policy
+source.
+
+## Live queue dashboard (#429)
+
+`/queue` loads open PRs and issues for the default registry project (seed:
+**Gitea-Tools** on `https://gitea.prgs.cc`) using existing `gitea_auth` read
+credentials. The UI surfaces pagination proof (returned count, pages fetched,
+`has_more`, `inventory_complete`) and classification badges (`claimed`,
+`blocked`, `in-review`, `duplicate`) when evidence exists.
+
+If credentials are missing or the fetch fails, the page shows an explicit error
+instead of an empty queue (fail closed).
+
+## Tests
+
+```bash
+pytest tests/test_webui_skeleton.py tests/test_webui_project_registry.py tests/test_webui_prompt_library.py tests/test_webui_queue_dashboard.py -q
+```

+
+For each failure, report:

+* failing test or error
+* suspected cause
