bug: CSV cliff_duration column is parsed but silently discarded, cliff never applied #234

Problem

lib/csv-parser.ts supports a cliff_duration header alias (line 29) and stores it on parsed rows (lines 157-159). However, the only consumer, app/app/create/batch/page.tsx:110-142, never reads source.cliff_duration — it only reads source.cliff_time.

Impact

A CSV that uses the cliff_duration column (a relative duration, presumably meant as an alternative to specifying an absolute cliff_time) silently produces a stream with no cliff at all — the value is parsed successfully but then dropped on the floor with zero validation error or warning shown to the person uploading the CSV. For a batch of payroll/vesting streams, this means cliffs that were supposed to apply simply don't, with no feedback that anything went wrong.

Suggested fix

Either implement the conversion from cliff_duration to an absolute cliff_time (relative to each row's start_time) in batch/page.tsx, or remove the cliff_duration alias from the parser entirely if it isn't meant to be supported, so the CSV template/docs don't advertise a column that does nothing.
