feat(net): track + echo movement sequence counters

Browse source 
Sprint 1a of the audit remediation plan.

Extracts the 4 movement sequence counters from inbound server messages
and echoes them in outbound MoveToState + AutonomousPosition instead
of hardcoded zeros:

- instanceSequence (slot 8 in CreateObject PhysicsData timestamps)
- teleportSequence (slot 4, also from PlayerTeleport 0xF751)
- serverControlSequence (slot 5)
- forcePositionSequence (slot 6, also from UpdatePosition 0xF748)

Source: holtburger player/types.rs:237-245, mutations.rs:182-706.
The server uses these to detect stale/reordered movement packets.
Previously all zeros → server couldn't distinguish epoch boundaries.

Changes:
- CreateObject.Parsed: +4 sequence fields extracted from timestamps
- UpdatePosition.Parsed: +3 sequence fields from trailing u16s
- WorldSession: tracks 4 counters, updates from CreateObject/
  UpdatePosition/PlayerTeleport for the player's own GUID
- GameWindow: passes tracked values to MoveToState.Build and
  AutonomousPosition.Build
