feat: clear a meal-plan day or the whole week in one action

New bulk-delete route for the owner's own weekStart-scoped plan
(mirrors recipes/bulk's DELETE), plus ?ids= support added to the
existing shared-plan DELETE route (kept ?entryId= working
unchanged). UI: hover-reveal trash icon per day header, "Clear week"
button in the toolbar, one shared confirm dialog for both.
