feat: resolveproject group in the segments middleware (CM-189)

[ulemons]

Note

Medium Risk
Changes request segment scoping by allowing project group/project IDs to be expanded to leaf subprojects server-side, which can affect data visibility and query results across many endpoints. Also adjusts activity querying and Tinybird parameter handling, with moderate risk of pagination/count discrepancies if segment expansion/capping is incorrect.

Overview
Segments handling is centralized in the backend. segmentMiddleware now ignores req.params, safely parses segments from query/body, and resolves any non-leaf segment IDs (project group/project) into their active leaf subprojects before setting currentSegments.

Frontend requests are simplified to pass project-group IDs. Multiple views (activity timeline, member/org lists, banners, filters, and the Axios interceptor) stop expanding project groups into subproject IDs client-side and instead send [selectedProjectGroup.id], relying on the middleware for expansion; the activity timeline also guards invalid joinedAt timestamps and can send an empty segments array.

Activity/Tinybird querying is hardened. The activities SQL path switches the count call to pipeSql, Tinybird activity params now cap the segments array (with a warning) to avoid Tinybird 400s on large groups, and Tinybird client logs non-retriable error details; noisy advanced-query cache info logs were removed for members/orgs background refreshes.

Pull request overview

This PR updates segment scoping so the frontend can send project group (non-leaf) segment IDs, and the backend middleware will resolve them into leaf sub-project segments for downstream queries.

Changes:

• Backend: enhance segmentMiddleware to expand non-leaf segment IDs into active leaf sub-project segments.
• Frontend: stop expanding project groups into subproject segments in a few call sites and instead pass [projectGroup.id].
• Frontend: adjust organization merge suggestions calls to use the selected project group ID.
