around lines 68 - 72, Extract the repeated import sequence into a helper
function (e.g., importEnvVars) that accepts parsed rows and performs the same
steps: use getValues("envVars") to filter out empty keys, map parsed rows to
include environmentId: defaultEnvironmentId, call reset({ envVars: [...existing,
...newRows] }, { keepDefaultValues: true }), call toast.success(`Imported
${parsed.length} variable(s)`), and call trigger(); then replace the three
duplicated blocks (the paste, text paste, and drop handlers) with a single call
to importEnvVars(parsed) so getValues, reset, toast.success, trigger and
defaultEnvironmentId are only referenced inside that helper.
