Build Activity Stream links for inventory source sync schedules

[blaipr]

SUMMARY

The Activity Stream description for a schedule belonging to an inventory source sync hit an explicit throw new Error('activity.summary_fields to build this url not implemented yet') and fell back to plain unlinked text — every other schedule parent (job template, workflow job template, project) gets a clickable link.

The blocker was that the inventory-source schedule route (/inventories/inventory/<inventory_id>/sources/<id>/schedules/<schedule_id>/) needs the parent inventory id, which the activity stream serializer didn't provide.

• API: ActivityStreamSerializer._summarize_parent_ujt now includes inventory_id when a schedule's parent unified job template is an InventorySource (the direct inventory_source summary gains it too, mirroring the existing group/inventory_id special case a few lines above).
• UI: ActivityStreamDescription builds the link from summary_fields.inventory_source, falling back to plain text when the id is unavailable rather than relying on a thrown exception for control flow.

Tests: a functional API test asserting inventory_id is serialized for an inventory-source schedule activity, and two UI tests (link built with the right href; graceful plain-text fallback for unknown parents).

Independent of all open PRs — no dependency or lockfile changes.

ADDITIONAL INFORMATION

Reproduce on main: create a schedule on an inventory source, then open the Activity Stream — the schedule entry renders as plain text instead of a link (the throw is caught upstream).

Pull request overview

This pull request fixes Activity Stream rendering for schedules belonging to inventory source syncs by providing the missing parent inventory_id in the API serializer and updating the UI to build the correct inventory-source schedule URL (with a safe plain-text fallback when the URL can’t be constructed).

Changes:

• API: Extend ActivityStreamSerializer schedule-parent summarization so inventory-source schedule activities include summary_fields.inventory_source[0].inventory_id.
• UI: Teach ActivityStreamDescription to build /inventories/inventory/<inventory_id>/sources/<source_id>/schedules/<schedule_id>/ links for inventory-source schedules without relying on an exception path.
• Tests: Add a functional API regression test and UI tests covering both link building and graceful fallback behavior.

Tested and the name is now properly linked in Activity Stream.
