Fix transitional icons by always storing pending transitions for visual feedback

- Store pending transitions even for redundant commands (start active service)
- Add 3-second timeout for redundant command visual feedback
- Include timestamp in pending transitions to enable timeout clearing
- Show directional arrows immediately regardless of command validation result
- Fix core issue where state validation prevented visual feedback storage

Now pressing s/S/r always shows immediate directional arrows, even for
redundant operations, providing consistent visual feedback to users.
