Fix RBTS timeout stake returns

[cursor]

Description

Fixes a high-severity RBTS timeout fallback bug where a round could settle after the oracle snapshot timeout without marking revealed voter stakes as returned.

Changes

• Return all revealed commit stakes on the empty-snapshot RBTS timeout path.
• Keep normal finalized snapshot/no-forfeit behavior weight-gated.
• Add a regression covering timeout settlement and subsequent voter stake claims.
