fix: prevent automatic quote correction in TOML input fields

- Remove unnecessary normalizeSmartQuotes function and its usage
- Add input attributes to prevent automatic text correction (inputMode, data-gramm, etc.)
- Delete unused textNormalization.ts utility file
- Keep user's original input without any quote transformation
