Incorrect Masking Behavior When SILKY_SENSITIVE_KEYS is Empty

[ahsanshafiq742]

In Django Silk, when SILKY_SENSITIVE_KEYS is set as an empty dictionary ({}), the expected behavior is that no values in the request body and headers should be masked, since masking should only apply to keys explicitly listed under SILKY_SENSITIVE_KEYS.

However, instead of allowing all request body values to remain visible, Django Silk incorrectly masks everything in the request body.

Expected Behavior:
If SILKY_SENSITIVE_KEYS is empty ({}), Django Silk should not mask any values in the request body.

Actual Behavior:
When SILKY_SENSITIVE_KEYS = {}, all request body values are masked, which is incorrect.

Steps to Reproduce:

• Set SILKY_SENSITIVE_KEYS = {} in Django settings.
• Make an API request with a request body containing various key-value pairs.
• Observe that all values in the request body are masked in the Django Silk logs, even though no keys are
  specified for masking.
• This issue affects data visibility in logs and may lead to unexpected debugging challenges.

I’d like to work on this issue. Can it be assigned to me?
