Summary

Adds an Activity tab to Teams and publishes Circles changes into the shared Nextcloud Activity stream.

What changed

• Add a Team Activity view with pagination, filters, rich Activity text, and navigation integration.
• Publish Circle activities using the Circle database ID as the Activity object, so Team Activity can scope them reliably.
• Record member changes, role changes, team title and description edits, and Team setting changes.
• Render setting activities with the specific setting and enabled/disabled state instead of a generic “changed setting” message.
• Add Team navigation support for Activity, Collectives, Deck boards, Team pages, and Team folders.

Implementation notes

• Resolves the numeric Activity object ID through CircleRequest using the Team's stable singleId.
• Description content is intentionally not stored in Activity events.
• Unknown or sensitive setting values remain generalized.
