[BUG] Single day Collections will think location visits are out of date range

[cjmlax]

Describe the bug
When a collection only lasts for one day and a valid visit is added it is still considered "Not in itinerary date range". Use case is for a single day trip to an event via morning and evening train.

To Reproduce
Steps to reproduce the behavior:

1. Create a Collection where the start and end dates are identical (eg Dec 25, 2025 and Dec 25, 2025)
2. Create or link a location to the collection.
3. After completing the rest of the details, add a visit on the same day as the collection.
4. The visit will appear in both itinerary views but still have the "Not in itinerary date range" tag.

Expected behavior
Location visits that share the date of the collection should not be tagged as "Not in itinerary date range".

This doesn't seem related to my config/deployment, but can provide if needed.

Additional context
I see a few other bugs that may be related, but wasn't sure if this would be fixed by those resolutions. I didn't see this particular symptom in any other reports so I'm adding it just in case.
