add ca fertilization harmonization and ncc compost support

[divine7022]

Description

folds standalone N fertilization harmonization (was living at /projectnb/dietzelab/ccmmf/management/fertilization/harmonization.R) into data.land data-raw pipeline, then layers ncc (compost) sampling support on top and extends the events schema with an ncc event type

events_schema_v0.1.2.json picks up ncc as an allowed event_type with material, ncc_subtype, fert_subtype, and pft properties

separate workflow PR will consume these samplers from workflows/fertilization-statewide and workflows/ncc-statewide to emit ensemble events
