fix(smoke): mcptoken — runtime gatewayUp gate + scope revocation case to HTTP-mode

Two bugs found while trying to point MCPGW_URL=http://localhost:3200
(the systemd mcplocal) so we could get real smoke coverage before the
Pulumi stack for mcp.ad.itaz.eu lands:

1. describe.skipIf(!gatewayUp) was evaluated at parse time, before
   beforeAll ran, so gatewayUp was always false and the whole suite
   skipped. Switched to the vllm-managed.test.ts pattern: runtime
   `if (!gatewayUp) return` at the start of each it().

2. The revocation 401 assertion only makes sense against the
   containerized serve.ts entry, which has a 5s negative introspection
   cache. Against systemd mcplocal the whole project router is cached
   for minutes, so a deleted token with a warm session still succeeds.
   Added IS_HTTP_MODE detection (hostname not localhost/127/0.0.0.0,
   or MCPGW_IS_HTTP_MODE=true) and skip the assertion otherwise — still
   revoking the token so cleanup runs identically.

Run against systemd mcplocal locally:

    MCPGW_URL=http://localhost:3200 pnpm --filter @mcpctl/mcplocal \\
      exec vitest run --config vitest.smoke.config.ts mcptoken

  → 6/6 pass (revocation case explicitly deferred).
