fix: tab reloads actually reload — kanban switch spam, plugins/skills refresh, ws mint (#897)

- ws: ticket-mint response body was read on the calling (main) thread —
  the socket read threw NetworkOnMainThreadException, the mint failed,
  and the kanban events stream never connected (board stuck Offline).
  execute() + body read now run entirely on Dispatchers.IO; same fix in
  DashboardSessionTokenRefresher.fetch (loopback mint path).
- kanban: re-selecting the already-active board reloads data and
  reconnects events WITHOUT the redundant POST /boards/{id}/switch that
  refresh fired on every tap.
- plugins: top-bar Refresh + pull-to-refresh wired through HermesScaffold
  (previously no reload control at all).
- skills: Refresh icon now does a plain GET reload; the heavy hub-update
  POST moved to the cloud icon so refresh is no longer disguised as update.
- test: mock the 3-arg Log.w overload (catch now logs the full stack).
