Code Review

This pull request adds support for the 'client_credentials' OAuth grant type to Salesforce plugins, including updates to documentation, UI widgets, and validation logic. Key feedback involves refining the field description for clarity, making the security token optional for the password grant type to support IP whitelisting, and re-adding null checks for authentication fields in the format providers to avoid potential NullPointerExceptions.

[gemini-code-assist]

The description mentions 'basic' as a grant type, but the supported values are 'password' and 'client_credentials'. It would be clearer to use 'password' instead of 'basic' to match the actual configuration values and the UI labels.

Suggested change

	@Description("Salesforce authentication grant type: basic or client credentials")
	@Description("Salesforce authentication grant type: password or client credentials")
