[#73798] Remove scrum_projects feature flag from Backlogs

[myabc]

Ticket

https://community.openproject.org/wp/73798

What are you trying to accomplish?

Remove the scrum_projects feature flag from Backlogs and make the sprint-based implementation permanent.

What approach did you choose and why?

The flag was already permanently active ("forced"), so the old branches were dead code. This PR:

• Removes the scrum_projects feature registration and the remaining flag checks
• Keeps the sprint-based Backlogs path and removes the legacy UI/controller/routes that were only needed before the flag was made permanent
• Deletes the Impediment model, services, controller (rb_impediments_controller), views, and all associated specs
• Strips the Task and Story models to bare STI stubs (all dead methods removed)
• Deletes rb_wikis_controller and its routing specs
• Removes the old jQuery Taskboard frontend chain, including its legacy Sass and TypeScript/Stimulus entrypoints
• Deletes dead patch files: type_patch.rb, versions/row_component_patch.rb, work_package_filter.rb
• Removes unused methods from work_package_patch.rb and slims version_patch.rb to just the has_many :version_settings association
• Strips all dead scopes and methods from Sprint < Version (now a bare shell; Agile::Sprint is the active model)
• Removes dead plugin settings (story/task/wiki template fields) and their classification hooks
• Keeps the rb_taskboards redirect endpoint so sprint links continue to resolve to the linked board
• Updates affected specs throughout to match the permanent sprint-based behavior

Important

This Pull Request also updates shared feature-spec helpers because removing scrum_projects makes the old Backlogs-enabled inline-edit path always active in feature specs. That exposes pre-existing Cuprite interaction issues outside the Backlogs specs themselves: ng-select fields may already have an open dropdown when the helper tries to click again, and multi-value chip removal can be overlapped by the option panel. The helper now reuses an already-open dropdown before clicking, targets the actual ng-select input, and keeps the Cuprite-specific fallback limited to the chip-removal path that still needs it. It also refreshes My Page drag targets after CDK drag updates the DOM.

Remaining cleanup (follow-up PRs)

The following items were identified during review but are out of scope for this PR:

• Full removal of the Task and Story STI stub models (depends on confirming no DB-level STI rows remain)
• Remove definition-of-done menu from backlogs_settings_form
• Delete backlogs/patches/status_patch.rb
• Audit remaining patch files for unused methods and remove them
• Consider removing backlogs/mixins/prevent_issue_sti.rb once Task/Story stubs are gone
• Check all remaining Backlog, Story, and Task type references

Pull request overview

Removes the scrum_projects feature decision from the Backlogs module and makes the sprint-based Backlogs (Agile::Sprint) behavior the default across UI routes, controllers, helpers, and API endpoints, with corresponding spec updates.

Changes:

• Removed scrum_projects feature decision registration and deleted feature-flag-dependent branches across Backlogs routes/controllers/API.
• Made sprint-based Backlogs behavior the default (Agile::Sprint), including routing and representer/schema exposure.
• Updated Backlogs and PDF export specs to align with the permanent sprint model and adjusted position/reordering behavior.

modules/backlogs/lib/open_project/backlogs/work_package_filter.rb:88

• backlogs_configured? is now hard-coded to false, which makes this filter permanently unavailable (available? will always be false when backlogs is enabled). Since the filter still contains SQL logic for story/task/impediment, this looks like dead/stranded code. Consider removing the filter (and any API/schema exposure) entirely if it’s no longer part of the sprint-based Backlogs model, or update it to reflect the new model so it remains usable.

    def backlogs_configured?
      false
    end

    def backlogs_enabled?
      project.nil? || project.module_enabled?(:backlogs)
    end

modules/backlogs/app/services/work_packages/rebuild_positions_service.rb:55

• When @project is provided, the UPDATE is filtered, but the mapping subquery still computes ROW_NUMBER() over the entire work_packages table. On large instances this can be unnecessarily expensive. Consider applying the same project condition inside the subquery (e.g., in the FROM work_packages part) so the window function only scans rows for the target project when @project is set.

@myabc copied from our chat:

is it ok to remove the global settings page? (Admin > Settings > Backlogs) It only shows a blankslate.

The blankslate should be kept. The idea was to keep the route alive even though all the options were removed in 17.3, because new settings will be added soon.

I've removed old APIv3 endpoints.

I assume you are referring to the removal of the BacklogTypeRepresenter. That change is fine.

We're still using Story.types and Task.type in a few places. I'm not sure if this PR should try to get rid (the UI for configuring is no longer reachable). Specifically, we need to check the logic here.

It should definitely be removed ASAP. We don't rely on it any more. Whether the removal is part of this PR or the next, I don't care.

I had to modify the rebuild positions service SQL (AI helped me with thiis), but am not sure about the change.

The change I could spot was adding the id to the order criteria: ORDER BY position, created_at, id. That should not be relevant in reality but I also don't see a problem doing it.

@dombesz this change is probably not necessary. However, it may future proof things for permissions.
