Fix automation exporter escaping for reliable Python/Node output

[TopProjectsCreator]

Motivation

• The automation pane generated Python/Node snippets by interpolating raw config values, which produced invalid code when users supplied quotes or special characters.
• Generated exporter snippets need to reliably serialize user-provided strings to avoid runtime/parsing errors in exported scripts.

Description

• Hardened code generation in src/components/ide/AutomationTemplatePane.tsx by replacing fragile direct interpolations with safe serialized literals using JSON.stringify for Python and Node snippets.
• Escaped provider-specific fields (models, email addresses, channels, chat IDs, repo/table names, voice IDs, currency, URLs) so generated code remains syntactically valid with arbitrary config values.
• Improved GitHub Node snippet by introducing owner/repo constants and encodeURIComponent use to avoid malformed request URLs for special-character names.
• Fixed a parsing error introduced during editing and ensured generator sets nodeCode/pythonCode correctly for the UI display.

Testing

• Ran npx eslint src/components/ide/AutomationTemplatePane.tsx which returned no parsing errors and only a few repo warnings in that file.
• Ran npm run test -- src/test/languageTemplates.test.ts and the test suite passed (1 file, 4 tests all passed).
• Ran npm run lint which shows pre-existing repo warnings but no new parsing errors introduced by this change.
