fix(ungated-global): create settings secret with a valid backend FK

bootstrapUngatedGlobal wrote its seed marker into the mcpctl-system-settings
Secret, creating the row with the default backendId '' when it did not exist.
The Secret_backendId_fkey constraint is enforced at insert time, so on a DB
where that secret was absent, mcpd crash-looped on startup (P2003).

Fix: run the seed after bootstrapSecretBackends (so the default plaintext
backend exists) and set backendId to the resolved default on create. If no
backend exists at all, skip writing the marker rather than crash.

+# ungated-global: servers under every project, before the gate
+
+`ungated-global` is a system project with one special property: **every server
+attached to it is exposed under every project's MCP endpoint, in front of the
+gate** — its tools are listed and callable before `begin_session`, and the
+project's `prompt` is prepended to every project's instructions.
+
+Fresh mcpd instances seed it **once** with the default `calcmcp` server
+(scientific calculator, patched fork of
+[thinkitpossible/CalcMCP](https://github.com/thinkitpossible/CalcMCP) at
+<https://mysources.co.uk/michal/CalcMCP>) and a prompt telling models to never
+do math themselves and always use calcmcp.
+
+## Semantics
+
+- **Seed-once, not resurrect**: the first successful mcpd startup writes
+  `ungatedGlobalSeeded: true` into the `mcpctl-system-settings` secret. After
+  that, nothing is ever re-created — deletions are durable:
+  - `mcpctl delete server calcmcp -p ungated-global` detaches the default
+    server (delete the server resource itself to also stop its instance);
+  - deleting the whole `ungated-global` project turns the feature off.
+  To re-create the default by hand there is a `calcmcp` template:
+  `mcpctl create server calcmcp --from-template calcmcp`, then attach it to
+  a (re-created) `ungated-global` project.
+- **Merging** happens in mcpd:
+  - `GET /api/v1/projects/:id/servers` appends ungated-global's servers,
+    flagged `ungatedGlobal: true`. A server attached to the project directly
+    wins (no duplicate, no flag).
+  - `GET /api/v1/projects/:id/instructions` prepends ungated-global's
+    `prompt` and appends its servers to the server list.
+- **Gate exemption** happens in mcplocal: discovery passes the flagged names
+  into the gate plugin (`ungatedServers`); while a session is gated,
+  `tools/list` returns `begin_session` **plus** the exempt servers' tools, and
+  calls to them pass through without triggering the gate intercept or
+  ungating the session. Initialize instructions list them under
+  "Available immediately (no begin_session required)".
+
+## Editing the prompt
+
+The pre-gate directive lives on the project itself:
+
+```bash
+mcpctl patch project ungated-global --prompt "…"
+```
+
+Caveat: clients that ignore MCP initialize instructions (e.g. LibreChat uses
+config-literal serverInstructions) never see project prompts — for those, the
+carrier is the tool/server descriptions themselves, which is why calcmcp's
+server description also says "use it for every mathematical calculation".
+
+## Security note
+
+Anything attached to ungated-global is reachable from **every** project by
+**every** token that can reach any project endpoint. Only attach servers that
+are safe in every context: no secrets, no egress, no side effects. calcmcp is
+pure compute (no env, no network).
