Pre-Scheduled Session Reservations

[Luluameh]

Background
Users want to book expert time slots in advance (e.g., "meet tomorrow at 3 PM"). Currently the contract only supports live on-demand sessions.
Goal
Implement a reserve_session(expert, token, rate_per_second, scheduled_start, duration_cap) function that locks funds in escrow until the scheduled time.
Acceptance Criteria

• New SessionStatus::Reserved state.
• Session auto-activates when ledger_time >= scheduled_start.
• Seeker can cancel before scheduled_start - 1 hour for a full refund.
• Late cancellation forfeits a configurable cancellation_fee_bps.
