v0.11.0 — Plant types: the reusable "kind" record

A rich-but-all-optional reference record per kind of plant (care, sun, water,
bloom & harvest windows, toxic-to-pets, edible parts, spacing), distinct from a
specific planting or a group.

- PlantType model + optional Plant.plantTypeId; migration + idempotent backfill
  that seeds 247 kinds from the built-in plant library and links plantings by
  species/common name (wired into the deploy entrypoint)
- /api/plant-types CRUD; new "Plant types" section (browse by category, edit a
  kind, see every spot you've planted it)
- New plants auto-link to their type on create; plant detail shows "More about…"
- PlantType added to backup/restore; bump APP_VERSION 0.11.0 + changelog
