Extends GET /api/v1/users/me/nutrition-diary with a `range` query
param (7/30/90) that switches it into trend mode -- daily
calorie/macro totals bucketed from the same cooking-history rows the
single-day diary already reads, with zero-filled days so the chart
has a continuous x-axis. New NutritionTrend component reuses the
existing hand-rolled TimeSeriesChart (previously admin-only, now
imported from user-facing code too) for the calorie line, plus
simple average-macro stat tiles below it.
Nutrition page now has Diary/Trend tabs instead of just the diary.

Six M-sized items from HANDOFF.md's new-features backlog:
- Profile tabs: cooking-history stats (total cooked, last-cooked, streak)
and a "cooked it" photo gallery, both owner-only
- Display-time unit conversion (metric<->imperial) for recipe ingredients,
respecting each user's unitPref; original value always shown alongside
the conversion
- Nutrition daily diary: per-day macro totals computed from cooking history
x recipe nutritionData, compared against user goals
- Pantry scan: real barcode lookup (zxing + Open Food Facts, no API key)
with an AI-vision fallback for unbarcoded items, always confirm-before-
insert, both paths tier/rate-limited like other AI features
- Weekly digest email: new followers/comments/ratings + trending recipes,
sent via a new `cron` Docker stage (alpine+crond+curl) and `digest-cron`
compose service hitting a bearer-token-protected internal route
- Meal-plan generation can now target a user's nutrition goals as a
prompt-level nudge (recipes are AI-invented, not DB-sourced, so this
can't be a hard macro constraint)
Caught a real deploy-breaking issue while adding the cron stage: appending
it after `runner` silently changed the Dockerfile's default build target,
and `web`'s compose config didn't pin one — fixed by pinning `target:
runner` explicitly. Verified with typecheck, lint, and three separate
`docker build --target` runs (runner/cron/migrator) plus `docker compose
config` validation.
