Timestamp now sits on its own line above each event so it's visually
separate from the change description. Field names use a friendly label
map (hardware_acceleration → hw acceleration, tailscale_ip → tailscale ip,
etc.). The created event reads "instance created" in accent colour instead
of a raw "created / —". Padding between rows increased.

Add a Display section to the settings modal with a timezone dropdown.
Selection is persisted to localStorage and applied to all timestamps via
fmtDate (date-only) and fmtDateFull (date + time + TZ abbreviation, e.g.
"Mar 28, 2026, 2:48 PM EDT"). Changing the timezone live-re-renders the
current page. Defaults to UTC.

Adds an instance_history table that records every field change:
- createInstance logs a 'created' event
- updateInstance diffs old vs new and logs one row per changed field
(name, state, stack, vmid, tailscale_ip, all service flags)
- History is stored under the new vmid when vmid changes
New endpoint: GET /api/instances/:vmid/history
The 'timestamps' section on the detail page is replaced with a
grid timeline showing timestamp | field | old → new for each event.
State changes are colour-coded (deployed=green, testing=amber,
degraded=red). Boolean service flags display as on/off.

Stacks are always just production/development — counting them adds
no useful information to the dashboard summary.

Adds a gear button to the nav that opens a settings modal with:
- Export: GET /api/export returns all instances as a JSON backup file
with a Content-Disposition attachment header
- Import: POST /api/import validates and bulk-replaces all instances;
client uses FileReader to POST the parsed JSON, with a confirm dialog
before destructive replace
