fix: form field alignment, raw maintenance text, and static movements list

- .form-grid labels (missing-field form, odometer-regression correction fields)
  and the odometer/overlap note textareas had no stacked label-above-input
  styling at all -- the shared rule only covered .filters/.return-form, so these
  fell back to default inline browser layout with mismatched input widths.
  Extended the existing rule to cover .form-grid and label:has(> textarea).

- Vehicle maintenance list showed the raw, untranslated seed text
  ("Synthetic scheduled service record") regardless of locale -- purely
  decorative and 1:1 redundant with the (already-translated) category. Replaced
  it with the record's real odometer reading, mirroring the sibling
  Inspections tab's pattern.

- "Today's movements" was always the same fixed 4 bookings (2 returns, 2
  departures) on every reset, reading as a static mockup rather than live
  fleet activity. Added 8 more bookings anchored to land on "today" across 8
  additional vehicles, spread through the day.
