fix(memtrack): prompt sudo on interactive stdin

[not-matthias]

validate_sudo_access previously checked stdin/stdout directly, so both redirected output and piped input could skip the password prompt even when the process still had a controlling terminal. The subsequent non-interactive sudo command then failed when credentials were not cached.

Use /dev/tty to detect whether sudo can prompt through the controlling terminal. Add a Linux integration test that launches a real Bash command with piped stdin and redirected stdout, then verifies a fake sudo receives --validate before the non-interactive command.

Fixes COD-3153

Greptile Summary

This PR fixes sudo prompting for memtrack runs when standard streams are redirected. The main changes are:

• Detects prompt support through the controlling terminal.
• Uses that detection before running sudo --validate.
• Adds a Linux test for piped stdin and redirected stdout.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
