Updated spectral version

Removed the Debug Request input from all action inputs. Debug logging is now controlled internally and no longer appears as a configurable field in actions.

Fixed an issue where the Key Pair Authentication connection applied unnecessary formatting to the Username field, which could cause JWT authentication failures for usernames that should not be uppercased or have dots replaced with hyphens.

Fixed an issue where the Execute SQL action failed when polling for async query results due to an incorrect API endpoint URL.

Changed the Passphrase field in the Key Pair Authentication connection to optional, allowing use of unencrypted private keys without entering a passphrase.
