Subject: [PATCH] fix(grafana): stop SI auto-scaling on km/hours stats; bound
 geomap to East Africa
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Grafana's lengthkm and h units auto-scale with SI prefixes — fleet km
totals rendered as "Mm" (megametres) and drive-hour totals as days/weeks,
which read as "millions" and "weeks" on the Daily Ops dashboard. Switched
the affected panels (Fleet km today, Drive/Idle hours today, the per-vehicle
roll-up table, the driver leaderboard, and the 7-day distance trend) to
unit "none" with decimals: 1 so values stay in km/h with units carried by
panel titles and column displayNames.

Geomap view recentred to lat -2.0, lon 35.5, zoom 5 with minZoom 5 /
maxZoom 12 so the Active Vehicles map opens on the East African Community
region and cannot zoom out past it.
