Fix unlocked doors/containers not opening after security changes

Fixed issue where unlocked doors and containers wouldn't open because
getLockRequirements functions returned null for unlocked items, causing
early return.

Changes:
- Handle case where lockRequirements is null (unlocked item) by calling
  server verification
- Updated getLockRequirementsForDoor to return data even for unlocked doors
- Updated getLockRequirementsForItem to include 'locked' field
- Now both locked and unlocked items go through proper server validation

Flow for unlocked items:
1. getLockRequirements returns null (no lock data) OR returns {locked: false}
2. Call notifyServerUnlock with method='unlocked'
3. Server validates item is actually unlocked in scenario_data
4. Server returns roomData (doors) or contents (containers)
5. Client proceeds to open/display content
