Subject: [PATCH] fix(fitness): seed body-part inputs from last record
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Placeholders and +/- fallback now use the most recent recorded
value per part; previously placeholders were hardcoded "—" and
+/- bumped from 0. Buttons step by 0.5 cm (manual input still
accepts 0.1 resolution).
