• Display remaining-quota percentage instead of used-quota in the Progress indicator
  - 100 % when quota is untouched, shown in green
  - Warn at ≤ 30 % (yellow) and at ≤ 10 % (red)
  - Hide internal label (`showInfo={false}`) and move the percentage text into the Tooltip
  - Switch Progress `size` to `small` for a lighter visual footprint

• Update Tooltip to list used, remaining, total quota and the new percentage value

• Uniformly set `size="small"` on all header Buttons and Form inputs within the table
  — enhances readability and keeps the main content centered

UI/UX improvement only; no backend logic affected.
