Period selection (date range, season, etc.) is now expressed as a
filter condition like any other — no separate date range section.
Preview uses a timeline/number-line bar instead of month chips.
Documents the unified filter builder approach.

Covers architecture, data model, API routes, SQL patterns, and UI design.
Includes baseline workbench design with multi-segment additive loads,
filter role for col_meta, and date offset for projecting actuals into
the forecast period.

The baseline operation now accepts a date_offset interval (e.g. "1 year",
"6 months") and applies it to every date when inserting rows, shifting
historical actuals into the target forecast period.
SQL: {date_col} + '{{date_offset}}'::interval)::date at insert time.
Route: defaults to '0 days' if omitted so existing calls are unaffected.
UI: year/month spinners with a live before→after month chip preview so
the projected landing period is visible before submitting.

Exposes the stored params (e.g. date_from/date_to for baseline/reference)
so the date range used in each operation is visible in the log.

Replaces the small inline form with a centred modal dialog. When both
dates are selected, a live chip list shows every month covered (up to
36 months) so it is immediately clear what periods will be loaded.

Instead of re-fetching all forecast data after scale/recode/clone/reference,
the routes now return the inserted rows directly. The frontend uses ag-Grid's
applyTransaction to add only the new rows, eliminating the full reload round-trip.
