## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
When keyboard-only mode is active, opening the subtitle sidebar should not disable controller navigation and lookup/mining controls. Restore controller input while the sidebar is open, while keeping true modal dialogs blocking controller actions.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 Opening the subtitle sidebar does not block controller input for keyboard-only mode actions.
- [x] #2 Controller-select/debug and other true modal dialogs still block controller actions while open.
- [x] #3 Focused regression coverage exists for the sidebar-open controller gating rule.
<!-- AC:END -->
## Implementation Notes
<!-- SECTION:NOTES:BEGIN -->
Root cause: renderer gamepad polling used the broad `isAnyModalOpen()` check as its interaction gate, and that list includes `subtitleSidebarModalOpen`. The subtitle sidebar is non-modal for controller usage, so gamepad input was being suppressed whenever the sidebar was visible.
Fixed by extracting a dedicated controller-interaction blocking helper that excludes the subtitle sidebar but keeps the existing blocking behavior for true modal dialogs.
<!-- SECTION:NOTES:END -->
## Final Summary
<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Restored controller input while the subtitle sidebar is open by switching gamepad polling to a dedicated modal-blocking rule that leaves the sidebar controller-passive. Added a regression test covering the sidebar-open exception and preserving hard blocks for actual modal dialogs.
