Add Stylus redeem filtering tests: execution rollback NIT-4607

[mahdy-nasr]

Add system tests for Stylus contract redeem filtering (NIT-4607). Verifies that the group rollback mechanism
from PR #4436 correctly handles Stylus (WASM) contracts. Two tests: SandwichRollback (L2 same-block sandwich via Pause/Activate), DelayedSandwichRollback (L1 delayed inbox halt/resume cycle).

Pull request overview

Adds new system test coverage to ensure redeem filtering group rollback behaves correctly when the redeem chain involves Stylus (WASM) contracts, including both same-block “sandwich” scenarios and delayed inbox halt/resume scenarios (NIT-4607).

Changes:

• Add two new Stylus-focused system tests covering rollback isolation within a block and delayed sequencer halt/resume behavior.
• Add helper routines to enable Stylus (chain ownership + ink price) and deploy a Stylus storage contract for the tests.
• Add a changelog entry documenting the internal test additions.
