feat: add include query param and sessions to unified /me endpoint

GET /v1/iam/users/me now supports ?include=hackathon,qr,mentor,sessions
to control which module profiles are returned. Omitting the param
returns all modules. Also added dimentorin sessions data.

Examples:
  /v1/iam/users/me                        → all modules
  /v1/iam/users/me?include=hackathon      → only hackathon profile
  /v1/iam/users/me?include=mentor,sessions → mentor + sessions only
