v0.24.0 — Garden: harvest→pantry, structured amounts, UW Extension links

Harvest logs now carry a structured amount+unit (legacy freeform quantity
kept for old rows) and can simultaneously create a GARDEN-source pantry
item via addPlantLog's new pantry input. PlantTypes can link a UW–Madison
Extension article, searched through /api/v1/plant-types/uw-search (proxy
to hort.extension.wisc.edu's WordPress REST API); the link shows on the
type page and each plant. The garden log dialog now posts to /api/v1.
