Add Hunter/Hider role selection on connect with role-scoped modes

Roles are chosen in the bootstrap dev panel before Host/Client. NGO
ConnectionApproval is enabled at runtime and maps the role payload to
the matching prefab variant per connection (Hunter/Hider), so each peer
spawns the correct avatar including the host.

- PlayerRole.cs (new): single source of truth enum { Hider, Hunter }.
- NetworkBootstrap.cs: role toggle, ConnectionApproval + role payload,
  server ApprovalCheck mapping role -> PrefabIdHash.
- NetworkPlayerSetup.cs: serialized PlayerRole field + Role property.
- GameModeManager.cs: BuildModes(role) - Hunter -> [First Person, Paint],
  Hider -> [Third Person, Paint, Free Cam]; binds role from spawned avatar.
- Hunter.prefab: role = Hunter override.
- SampleScene.unity: NetworkBootstrap prefab references wired.

Also includes user inspector scale tuning (Hunter 2.5->2.4, Hider 0.5->0.7).
