test(orchestrator): stabilize decrypt TUI end-to-end tests

Reduces flakiness in the decrypt TUI end-to-end tests when run
with coverage enabled or under package-level load.

- increases simulated input delays
- extends end-to-end test timeouts and contexts
- avoids false negatives without changing production code
