Retire the Dashboard tab; Processes is the front page

The app repeated itself. The module list, /api/prefs/dashboard, applyPrefs and the
per-user dashboard blob are gone. Widgets stays and now says plainly that it is for
dashboards outside Ham Lab.

This also closes a bug: applyPrefs set the sampling rate from intervalMs inside the
dashboard layout, and reset it to the default when that field was absent — so with
per-user layouts, one account saving a dashboard could reset the sampling rate for the
whole machine. The sampler now has one source.

+  id and its route are gone. A rail order saved before this keeps its shape — `railorder.ts`

+- **Dashboard retired** — **2026-09-23**, at Mitchell's instruction, the same reasoning that
+  merged Top into Processes: the app repeated itself. The customisable module list is gone
+  (`Dashboard.tsx` deleted), and with it `/api/prefs/dashboard`, `applyPrefs`, and the
+  per-user `dashboard` blob in `state.json`. The Processes tab already shows those numbers
+  on one screen. `fmtBytes`/`fmtRate` moved to `fmt.ts` (Disks, Files and Space use them);
+  `MONITOR_HISTORY` and `seriesOf` went with the page. The default view after login, after
+  switching machines, and when a hub-only page is left behind, is now **Processes**. A saved
+  rail order naming `dashboard` degrades quietly — `orderBy` drops ids with no page.
+  **Widgets stays and says what it is for**: a notice at the top explains these are for
+  dashboards *outside* Ham Lab — Glance, Home Assistant, a wall display — served from
+  `/embed/widget` with a read-only sensor token, not a second copy of the console's screens.
+  **It also closed a real bug.** `applyPrefs` set the machine's sampling rate from
+  `intervalMs` inside the dashboard layout, and its `else` branch reset the sampler to the
+  default whenever that field was absent. Since layouts became per-user, one account saving
+  a dashboard could silently reset the sampling rate for the whole machine, overriding the
+  fleet refresh rate set in Settings. The sampler now has one source: `refreshMs` in the UI
+  prefs, which the hub fans out, remembered per machine as `sampler_ms`.

+- **Rename the Space tab** — asked for 2026-09-23, not started. "Space" is vague; the tab
+  is WizTree for a disk or pool. Candidates: **Usage**, **Disk Usage**, **Storage**. Note
+  `Disks` already exists and `Storage` would muddle with it, so Usage is probably the one.
+  The rename touches the rail label, the `View` id, the hash route (`#/<machine>/space`,
+  which people may have bookmarked — decide whether to keep `space` as the id and change
+  only the label), the footer's page name and `Space.tsx`'s own strings.
+
+- **ZFS gets its own tab, under Disks** — asked for 2026-09-23, not started. Today ZFS is a
+  section inside `Disks.tsx`: pools with health, capacity, fragmentation, scrub controls, a
+  dataset tree and per-dataset snapshot lists with "Snapshot now". Moving it out makes room
+  for what is actually wanted: **scheduled snapshots with a retention policy**, configured
+  from the console rather than by hand. What exists to build on — `grid` runs `zfSnap`
+  nightly at 02:30 from root cron with 6-week expiry (`zfsnap-cron-6w-daily.sh`, predates
+  this repo), and Ham Lab's Cron tab can already read, write and run root crontabs, so the
+  job can be managed rather than reinvented. Decide: does Ham Lab drive `zfSnap`/`zfs-auto-
+  snapshot` if present, or write and own its own timer? Per-dataset policies or one for the
+  pool? And it must show what a retention rule *will* delete before it runs.
+
+- **Rename Cron to something generic** — asked for 2026-09-23, not started. Mitchell's
+  reasoning: the Services tab is systemd but "Services" is the right generic name for it,
+  so the scheduling tab should be named for the job it does, not the tool. **Scheduled** or
+  **Jobs**. The tab already covers more than cron — `/etc/crontab`, `/etc/cron.d`, user
+  crontabs, `run-parts` directories *and* systemd timers — so the generic name is the
+  honest one. Same rename surface as the Space tab: rail label, `View` id, hash route,
+  footer name.
+
+- **A Virtualization tab** — asked for 2026-09-23, not started, and **large**. Run and
+  manage **LXC containers and virtual machines** from the console, the way Proxmox does —
+  which is the comparison Ham Lab has invited since its first line. Nothing exists yet.
+  What a future session has to settle before writing code: which stack (libvirt/KVM +
+  `virsh` is the obvious one for VMs; LXC or Incus for containers, and Incus covers both);
+  whether it manages what is already installed or installs it; where disk images live
+  (`tank` on `grid`, local NVMe elsewhere); console access (SPICE/VNC proxied through the
+  daemon, or a serial console over the existing terminal machinery, which would reuse
+  `internal/term`); snapshots and clones; and what it does on a host with no virtualisation
+  at all, which is every host here today. Worth scoping as its own plan before starting.
+
+- **Files explorer: cleanup and ease of use** — asked for 2026-09-23, not started.
+  General polish and ease of use. The **Deprecate copyparty**
+  item names the heavier pieces (multi-select and bulk actions, folder download, resumable
+  uploads, a gallery, search) — worth doing the two together, since they are the same tab.
