Align the expected message with the production diagnostic.
mixed_tstring_literal_error still returns the lowercase message at Line 4038. These expectations require "Cannot...", so both test cases fail. Update the production message to uppercase if that is the intended CPython behavior; otherwise restore the lowercase expectations.

Set the actual argument-list range.
ast::Arguments::range must span the opening and closing parentheses. The current assignment sets its start to the callee start, so l_paren_range() and inner_range() return incorrect offsets. ExprCall::range() already uses range_start for the callee and only needs arguments.end() for the call end.
Construct arguments.range with the actual opening-parenthesis offset and range.end(). Do not retain the merged range start because the conversion currently initializes it to an empty range.
