feat: HQ Toast + Confirm dialog primitives, replace browser alert()/confirm()

The Operations Inbox panel was using browser-native alert() and
confirm() — those popups break out of the dark-themed CMS aesthetic
and look like a 1998 form validation. Worse, they're modal blocking,
so the editor can't see the surrounding context (the ticket card,
the activity feed) while the dialog is up.

NEW PRIMITIVES (src/components/hq/Toast.tsx)
- <HqUiProvider> mounts a global toast stack (bottom-right) and a
  global confirm dialog. Mounted in src/app/hq-command/layout.tsx so
  every panel under /hq-command/* can use it.
- useHqUi() returns { toast, confirm }:
    ui.toast("Saved", "success")        // ephemeral, 3s
    ui.toast("Save failed: ...", "error")  // 5s
    await ui.confirm({                     // returns boolean
      title: "Delete ticket",
      message: "This permanently...",
      confirmLabel: "Delete",
      destructive: true,
    })
- Toasts auto-dismiss with a manual close button. Confirm dialog
  uses red accent for destructive actions.
- Zero deps. ~140 lines total.

INBOX (src/app/hq-command/dashboard/inbox/page.tsx)
- All 5 alert() calls replaced with ui.toast() — success / error
  toned and persisting just long enough to read.
- All 4 confirm() calls replaced with ui.confirm() — destructive
  ones (delete ticket, purge files, delete client) get the red
  accent + 'cannot be undone' copy.
- Action descriptions are richer ('Resolve & purge attachments'
  instead of 'Resolve') so the editor knows exactly what fires.

NO BACKEND CHANGES. Pure UX layer on top of the existing actions.
