perf: parallelize DB queries across routes, clean up fitness UI
Parallelize sequential DB queries in 11 API routes and page loaders
using Promise.all — measurements/latest, stats/overview, goal streak,
exercises, sessions, task stats, monthly expenses, icon page, offline-db.
Move calorie tracking out of /fitness/measure (now under /fitness/nutrition
only). Remove fade-in entrance animations from nutrition page.
Progressive streak computation: scan 3 months first, widen only if needed.
Bump versions to 1.1.1 / 0.2.1.
