feat: Mongo-backed Pods with full CRUD + member management

Pods are persisted in MongoDB and CRUD'd via /api/pods (list/create/get/
update/delete + add/remove member). Shared Pod reshaped to a persisted entity
(members: string[], description, timestamps) + PodInput. Backend seeds Demo/
Frontend/Backend Pods on first run (Squad -> Pod rename). Frontend replaces
hardcoded teams with live data: PodCard (member chips add/remove, inline edit,
delete, join) + CreatePodForm; App fetches+mutates via API. Removes teams.ts/
TeamCard; gitignores test artifacts.
