/**
|
|
* Parse and validate optional `from_date` / `to_date` query params for the
|
|
* date-range-aware financial reports (resultat- and balansrapport).
|
|
*
|
|
* Returns the bounds clamped against the fiscal period. Both params are
|
|
* optional: when omitted, the report falls back to the period as a whole.
|
|
* Returns a `{ error }` shape on invalid input so callers can map it to a
|
|
* 400 response without each route duplicating the same checks.
