fix: replace garbled mojibake characters with clean ASCII in comments

[57388sp]

Fixed CP1252/UTF-8 encoding corruption in comments across 3 scripts. Em dashes (—), ellipsis (…), arrows (→), and box-drawing divider lines were rendered as garbled sequences (e.g. ΓÇö). Replaced with standard ASCII equivalents (-, ..., ->). No logic changes.

Test Report missing or unfilled.

This PR touches python/, ansible/, or terraform/, so a populated Test Report section is required in the PR body. See TESTING.md for what to capture (environment, ONTAP version, first-run output, idempotency check, teardown).

This is a soft gate - your CI checks are unaffected - but reviewers will not approve until the report is filled in.
