Subject: [PATCH] Add zoom level helper and use it for cell sizing

Introduce a new `zoom_level` module containing the `CellSizes` enum and
`cell_size_helper` function to map `ZoomLevel` values to width and
height
dimensions. Export the helper from `mod.rs` and refactor `BoardWidget`
to
import and use `cell_size_helper`, eliminating duplicated match
statements.
