refactor(cloud-agent): determine session type from transport resolution

Add onResolved callback to CloudAgentSession that fires after
resolveSession completes in resolveAndConnect. The session manager
now derives activeSessionType from the authoritative ResolvedSession
(cloudAgentSessionId + isLive) instead of inferring it indirectly
from FetchedSessionData or onFirstActivity heuristics.
