Add Story Map Tool

[ishaanjain5]

Proposed changes

Feature request details: #595

Add a new Story Map feature for dashboards, with both backend and frontend creation/playback support.

On the backend, dashboards can now store Story Map configuration, including whether the feature is enabled, the story page structure, and individual story pages linked to dashboard bookmarks. Story pages support title, description, thumbnail, ordering, visibility, and bookmark association. The dashboard serializer, API response, form handling, save flow, and duplication flow were updated so Story Map data is preserved correctly across all operations.

On the frontend, dashboard admins can now configure Story Map pages from a dedicated Story Map tab in the dashboard editor. They can enable the feature, add/edit story pages, attach thumbnails, write descriptions, and connect each page to a spatial bookmark. On the viewer side, dashboards show a Story Map toolbar control and left-panel story experience with page navigation, autoplay, bookmark-driven map state changes, and toggle behavior that returns the user to the normal layer/filter tabs when Story Map is turned off.

This PR is a new feature. It also includes a number of follow-up fixes to make the feature usable end-to-end, including admin tab visibility, runtime title rendering, autoplay behavior, control icon visibility, and toolbar toggle behavior.

Thank you so much @ishaanjain5
Looks good to me, but could you merge migrations file as 1 file? (just to prevent big number of migrations file)

Also @janbur
I think i need to help @ishaanjain5 to:

1. Fix the python lint
2. Create E2E tests

Should i handle it or maybe we can ask @ishaanjain5 to work on it?

[janbur]

Great work @ishaanjain5 ! Let us know if you need support in fixing the Python lint or e2e.

Hi @ishaanjain5
Could you pull the main branch?
There is conflict and also some updates

I have put some new e2e tests to test some navigation, to also test this PR

[ishaanjain5]

Thanks for the feedback @janbur @meomancer. I went back to try and fix some of the issues you spoke about. Could you try rerunning the check? Thank you!

Hi @ishaanjain5
We have changed the github workflow
Could you pull the main branch? Should be no conflict

Thank you

[ishaanjain5]

@meomancer I understand. I pulled the main branch.

[ishaanjain5]

@meomancer I edited the code to fix the test that was failing. Can you try rerunning the check? Thank you.
