fix(migrations): scope v0.32.2 dirty-check to targeted sources; surface failed phase detail

- phaseBFenceFacts now queries legacy rows FIRST and dirty-checks only
  the source_ids it will actually write into. Zero fenceable rows (or
  rows scoped to clean sources) no longer fail on an unrelated dirty
  source. Targeted-dirty-source refusal unchanged. Fixes #927.
- apply-migrations now prints each failed phase's name + detail to
  stderr alongside 'reported status=failed', instead of burying the
  actionable message in the ledger. Fixes #921.
