Add budget-adherence calendar, streaks, and freely-editable synced budget
Both platforms gain a calendar tab/screen (green/yellow/red/not-logged
day coloring, logging/adherence streaks, year-to-date tally), and
tapping a day drills into that day's logged entries. This requires the
daily budget to become a normal, freely-editable value synced between
devices like the food log — replaces the previous chattr +i seal
(deliberately, per user decision) with plain last-edit-wins sync via a
new budget.json alongside food_log.json. The budget field defaults to
2200 kcal, starts read-only, and unlocks via an Edit/Save toggle on
both the PC gate's History tab and the phone app's Calendar screen.

// `backgroundSyncPush` is the unit-testable half of the connectivity-gated
// WorkManager backstop; the dispatcher branch and the one-off registration
// itself are integration-only (real WorkManager isolate, on-device smoke
// test) and excluded from coverage, exactly like the periodic check.
