What this PR does

Fixes #2176

When the indent filter is called with first=True and blank=False (the default), an empty first line was incorrectly indented.

Environment().from_string("{% filter indent(4, first=True) %}{% endfilter %}").render()
# Expected: ""
# Actual: "    "

Fix

In do_indent(), the first=True branch now checks if the result is non-empty (or if blank=True) before adding indentation:

if first:
    if blank or rv:
        rv = indention + rv

This ensures blank=False takes precedence over first=True for empty lines.

Test

Added test_indent_first_empty_no_blank to verify empty strings are not indented when first=True and blank=False.
