P1-27: Add host flow — form + minted-token result page

Browse Source 
GET /hosts/new renders the focused two-column form (hostname,
tags, repo URL/username/password). POST /hosts/new validates,
mints a one-time token via the new mintEnrollmentToken helper —
shared with the existing JSON /api/enrollment-tokens endpoint —
and re-renders the same page in result state showing:

  - the install command with RM_SERVER + RM_TOKEN filled in (and
    an inline copy-to-clipboard button),
  - an "awaiting agent connection" panel with the hostname
    pre-filled,
  - a troubleshooting list pointing at the most common reasons
    the agent doesn't appear,
  - back-to-dashboard / add-another-host links.

publicURL() resolves RM_BASE_URL first, falling back to scheme +
Host on the inbound request — useful for local smoke without a
proxy.

Browser-verified end-to-end: form submit → token minted → install
command renders with the right values from the form input.

template fn formatRelTime now accepts time.Time *or* *time.Time
so templates can pass either without fighting Go's lack of an
address-of operator.

Deferred: download-preconfigured-installer (a templated .sh with
the values baked in) — copy-paste covers v1; nice-to-have later.

- [x] **P1-24** (M) Dashboard: fleet summary tiles + host table (status dot + row accent + os/arch + last backup + repo size + snapshots + alerts + tags + run-now). Backed by `GET /api/hosts` + `GET /api/fleet/summary` (JSON) and a server-rendered HTML view. Empty state hands the operator the install command. HTMX `Run now` button posts to `/hosts/{id}/run-backup`.

UrBackup Internet-mode push installer). Encrypted repo creds ride on the token row and get pushed to the agent on first WS connect (see secrets/keyring task).
