Subject: [PATCH] fix(measurements): preserve decimal precision on non-grouped
 list rows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The v1.4.37 W7c collapsed list view passed every value through
`fmt.integer`, which kept the per-day step / activity aggregates
correct but silently truncated single weight / body-fat /
body-temperature readings — 78.4 kg rendered as "78 kg" on the
desktop table and the mobile card grid.

Grouped rows (`isGrouped === true`, the daily aggregate for
cumulative HK types) keep `fmt.integer` because the underlying
readings are integer-only by definition. Non-grouped single readings
now use `fmt.number(value)` which honours up to three fraction
digits without forcing a minimum, so 78 stays "78" and 78.4 renders
as "78.4" / "78,4" depending on the active UI locale.
