# Warn if milestone due date is in the past or far in the future

## Problem

When setting up milestones in either the milestones batch wizard or the contracts wizard, admins could accidentally enter a due date that is in the past or unreasonably far in the future (e.g. a typo resulting in a date decades away). There was no feedback to alert them to a potentially incorrect date.

## Solution

A non-blocking warning message is now displayed below the due date field whenever a milestone is saved with a date that appears incorrect. The warning does not prevent the admin from saving — it simply draws attention to the value so they can verify it is intentional.

## How it works

After a milestone's due date is autosaved, the system checks the date:

* If the due date is **in the past**, a warning is shown: "Warning: this due date is in the past"
* If the due date is **more than 5 years in the future**, a warning is shown: "Warning: this due date is more than 5 years in the future"
* Otherwise, no warning is displayed

The warning appears inline below the due date field and clears automatically when the date is corrected.

## UI

A yellow/orange warning message appears directly beneath the due date input field in both:

* The **milestones batch wizard** (milestone batches)
* The **contracts wizard** milestones step (contract milestones)

The warning is informational only and does not block saving or progressing through the wizard.
