Use the core {do} tag instead of {php} in templates

[dg]

All six occurrences are plain expression statements, which is exactly what {do} does. In Latte 3 the {php} tag lives in the opt-in RawPhpExtension, which this package neither requires nor registers, so the templates now work without it.

File	Description
src/templates/datagrid.latte	Replaces {php} statements with {do} to avoid requiring RawPhpExtension under Latte 3.
src/templates/datagrid_tree.latte	Same {php} → {do} replacement for tree rendering templates to keep them working under Latte 3 defaults.

Suppressed comments (1)

src/templates/datagrid_tree.latte:101

• Use {var ...} for variable assignment. {do} is better reserved for side-effect expressions; using it for assignments is less idiomatic and inconsistent with other templates in this repo (which use {var $x = ...}).

									{do $column = $row->applyColumnCallback($key, clone $column)}
