  grass.script.array: Auto-detect dtype from raster map type (#7105)

When reading a raster map into garray.array() or garray.array3d() without specifying dtype, the array now automatically matches the map's native type (CELL→int32, FCELL→float32, DCELL→float64) by querying r.info/r3.info with format="json". Previously, the default was always np.double, so reading an integer map would silently give you a float64 array. The default for empty arrays (no mapname) remains np.double.

Additionally, 64-bit integers are now rejected early with actionable error messages in both read and write paths, since
GRASS raster maps only support 32-bit integers.

Tests added, they revealed missing env in array3d.
