Edward Langley 5df3f87bc1 refactor(view): unify cell handling for records and pivot modes
Unifies cell text retrieval and formatting across pivot and records modes.
Introduces `GridLayout::display_text` to centralize how cell content is
resolved, reducing duplication in `GridWidget` and `export_csv`.
Moves formatting logic from `src/ui/grid.rs` to a new dedicated `src/format.rs`
module to improve reusability.
