- col_meta gets dim_period_col field: maps a dimension column to its pf.dim_period counterpart (e.g. year -> cal_year, month -> cal_month)
- When the date column is is_key of a dim_group and any sibling dimension has dim_period_col set, baseline and reference SQL JOIN pf.dim_period on the shifted date instead of copying raw source values
- No dim_period config = identical SQL to before (fully backwards compatible)
- Setup UI: period col input in col_meta editor, enabled for dimension columns with a dim_group set
- Schema migration applied: dim_period_col text null on pf.col_meta

- col_meta: add dim_group field to group related columns (dimension hierarchies, date-adjacent columns); is_key now enabled for date role to mark group parent
- sources.js: upsert includes dim_group
- Setup.jsx: group column in col_meta editor, key checkbox enabled for date role
- gen_dim_period.sql: create and populate pf.dim_period with calendar and fiscal period cuts (monthly grain, 2018-2035)

Forecast falls back to a saved per-source layout when no version-local
layout is cached, so new versions of a source open with a sensible pivot
without each user reconfiguring it.
