fix(flow-debugger): refuse method-entry Live runs for site-scoped users (#55)

Owner decision (b), 2026-11-09. An inbound API method has no site
affinity, so the F2 route-time scope only bounded routed SITE traffic;
the method's central-side effects (Database.*, ExternalSystem,
notifications) still ran for a scoped Deployer. FlowDebugRunner now
refuses FlowDebugRunMethodCommand for a site-scoped caller (site ids,
not Administrator) before the script executes, audits the refusal as a
failed InboundRequest under the operator's name, and raises
SiteScopeViolationException -> ManagementUnauthorized, so the Central
UI and the CLI (same /management command) share the gate.

The page disables the "Inbound API method" entry for scoped Deployers
with the reason (tooltip + inline note), starts them on script entry,
and ignores ?methodId= / a stored method choice. Replay and the
instance-scoped script / value-change Live runs are unchanged. The
route-time scope is kept as defence in depth.

Tests: scoped refused (in- and out-of-scope routing; script never runs,
refusal audited), unscoped/Administrator allowed, scoped Replay allowed,
scoped in-scope value-change Live still runs; bUnit for the disabled
entry, the drill-in, and the unscoped control. Mutation-proven (gate
and UI flag reverted -> 4 red).
