The live PB fixed_costs collection never received the is_recurring field
added in 87bb179 — the bootstrap script is collection-create-only and
errors out on already-existing collections, and no migration added the
field. Smoke-test rows sent is_recurring=false and got it silently
dropped (PB ignores unknown fields on write), then the partition helper
treated the missing value as monthly (its !=== false fallback).
Two changes:
1. Drop 'default: true' from the bootstrap schema definition. A bool
default only applies when the field is absent from the write payload,
so this is belt-and-braces — but it removes any doubt that a default
could ever silently override an explicit false. The partition helper
still treats absent values as monthly, and the backfill migration
patches pre-existing rows to true.
2. Make the backfill migration self-contained: if the field is missing
from the collection, add it (bool, required=false, no default) before
patching rows. Idempotent — no-op if already present.
