feat: icon+tooltip buttons on meal-plan/shopping-list headers (v0.28.0)

Match the recipe detail page's action-row convention: Share, Generate
shopping list, Shopping lists link, Print, Export to calendar, and
Send to grocery delivery collapse to icon-only with a tooltip instead
of icon+text, freeing up header space. Week prev/next arrows moved
next to the week date instead of sitting at the end of the button row.

Note: verified via typecheck/lint only — this dev environment has no
authenticated session to visually confirm in-browser.
