* Add helper scripts to update forks

* fix: improve HTTP Local URL validation UX and styling specificity

- Rename CSS class from generic "error" to "http-local-url-error" for better specificity
- Rename "invalid-url" class to "http-local-invalid-url" for clarity
- Disable httpServerCommandField when URL is invalid or transport not HTTP Local
- Clear field value and tooltip when showing validation errors
- Ensure field is re-enabled when URL becomes valid
