SQLite datetime('now') returns 'YYYY-MM-DD HH:MM:SS' with no timezone
marker. JS was treating this as local time, so timestamps showed the
correct UTC digits but with the local TZ abbreviation attached (e.g.
'7:15 PM EDT' when the real local time was '3:15 PM EDT').
Add parseUtc() which appends 'Z' before parsing any string that has no
existing timezone marker, ensuring JS always treats them as UTC before
the display-timezone conversion is applied.

nav-count was only set in renderDashboard, so loading /instance/:vmid
directly left it showing "—". Add getInstances() to the parallel fetch
in renderDetailPage and set the count there too.

Each event is now one row: label · old → new on the left, timestamp
right-aligned. Nothing is far from anything else. State changes use the
existing badge component for immediate visual recognition. The created
event reads 'instance created' in accent. Middle-dot separator keeps
field label and change value clearly associated without forced spacing.

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

Production images continue to display the semver (v1.x.x). Dev images
built by CI now receive BUILD_VERSION=dev-<7-char-sha> via a Docker ARG,
and app.js skips the v prefix for non-semver strings.
