fix(broker): show mesh slugs in /meshes + /status, remove all-meshes fallback

- /meshes and /status now show mesh slug names instead of truncated IDs
- meshSlug cached on connect and loaded from DB join on boot
- Remove dangerous fallback that connected to ALL meshes in email flow
- BridgeRow now includes optional meshSlug field
