Revert header button to Docker restart, remove TableControl Reset button

- Layout.tsx: Revert handleRestart to restart Docker containers (with confirmation)
- Layout.tsx: Change labels back to "Restart Docker"
- TableControlPage.tsx: Remove Reset button (keep only Home and Stop)
- TableControlPage.tsx: Remove handleSoftReset function
- TableControlPage.tsx: Remove client-side check blocking Home button
