fix(cli): apply a server's persisted mcp.json metadata

The web client and the TUI both read `savedSettings.metadata` and pass it
as `InspectorClientOptions.defaultMetadata`. The CLI never did, and
`InspectorClient` only reads the option rather than falling back to
`serverSettings.metadata` — so a per-server `metadata` entry was silently
inert for `--cli` runs.

Pass it beside the existing `roots:`, guarded on a non-empty map the same
way web and the TUI guard theirs, so `{}` still means "no defaults".
Precedence is unchanged: call-time keys override defaults in `mergeMeta`,
so `--metadata` stays per-invocation and wins on a key collision.

Covered by three catalog-driven tests asserting against the test server's
recorded wire requests. `createTestConfig` is retyped `StoredMCPServer` —
the accurate on-disk shape — since a fixture that cannot express the
per-server keys cannot cover the settings that reach the client.

Closes #2093
