feat(tracker-web): dynamic, owner-scoped project switcher via /products/mine

Wires the switcher to real per-user data instead of a static list:

- New /api/products/[...path] proxy to platform-service (mirrors the fleet
  proxy), exposing GET /api/products/mine.
- ProductProvider fetches the caller's owner-scoped projects on mount (when a
  tracker_token is present) and uses them as the switcher list. Best-effort:
  any failure / empty result / unauthenticated state keeps the configured
  fallback list, so dev and logged-out rendering still work.

Combined with the earlier config-driven list + auto-hide, the switcher now
reflects the authenticated user's projects on a generic platform.
