[FIX] dashboard: properly handle grid resize in dashboard mode

Before this commit:
- The canvas size was computed from the grid, which caused visible white margins
  after a snappy resize (commit 3c8df4b).
- Some unused props were being passed, creating unnecessary code clutter.

After this commit:
- The dashboard canvas size is now computed as the min of the grid bounds and
  the end of getColDimension.
- Shows only visible parts and avoids extra canvas processing.
