feat: activityRelations_data_copilot pipe

[epipav]

Changes proposed ✍️

Adds a new activityRelations_data_copilot pipe for data copilot.

It gets its data from activityRelations_deduplicated_cleaned_ds. The only difference from the raw data source is that fields that contain PII (username and objectMemberUsername) are omitted from the result set. Agents will use this pipe instead of the raw data source when they need raw data.

Checklist ✅

• Label appropriately with Feature, Improvement, or Bug.
• Add screenshots to the PR description for relevant FE changes
• New backend functionality has been unit-tested.
• API documentation has been updated (if necessary) (see docs on API documentation).
• Quality standards are met.

I noticed you're getting the isContribution column but I don't know how or if is being used by whoever consumes this pipe. We're going to be removing this column soon, so if it's being used, we need to have a plan for how to change this.

Also, the entire tinybird-ci.yml file is commented out but there's no mention of that in the PR description, so I'm wondering if this was by mistake.
