Add missing secondary role settings to user config (version 14)

[kareltucek]

Agent changes needed for user config version 14

Serialization (Agent writes config)

1. Bump written config version to 14.0.0
2. Version 7 block changes (same byte positions, same byte count):
   - triggeringEvent: change from Bool (0=Press, 1=Release) to UInt8 (0=Press, 1=Release, 2=None)
   - timeoutAction: UInt8 now accepts value 2 for None (was only 0=Primary, 1=Secondary)
3. After the version 10 block, serialize 4 new bytes:
   - triggerByMouse: Bool (1 byte)
   - acceptTriggersFromSameHalf: Bool (1 byte)
   - minimumHoldTime: UInt8 (1 byte, 0-255)
   - timeoutType: UInt8 (1 byte, 0=Active, 1=Passive)

Deserialization (Agent reads config)

• Version 7-13 configs: read TriggeringEvent as Bool (old mapping), skip 4 new fields (use defaults)
• Version 14+ configs: read TriggeringEvent as UInt8 (new mapping), read 4 new bytes after version 10 block

UI

• Expose 4 new settings in the secondary role advanced configuration:
  • Trigger by mouse (checkbox/toggle)
  • Accept triggers from same half (checkbox/toggle)
  • Minimum hold time (0-255ms slider/input)
  • Timeout type (Active/Passive dropdown)
• Update Triggering event to dropdown with values Press,Release,None
• Update Timeout action to dropdown to include Primary,Secondary,None
