Fix parsing issues with binary control characters

- Update alias parsing to handle binary control characters in Docker output
- Fix email accounts parsing to be more resilient to special characters
- Replace startsWith check with includes for more reliable matching
- Add regex clean-up to remove control characters (0x00-0x1F, 0x7F-0x9F)
- Remove strict ^ anchor from regex to allow parsing entries with prefixed binary data
