Trim user input before sending to detectSQLInjection

[bitterpanda63]

Trims leading/trailing whitespace from user input before SQL injection detection, matching the fix applied to the Java firewall in AikidoSec/firewall-java#298.

Problem: An attacker can pad their payload with trailing whitespace (e.g. "payload "). If the DB driver trims this before execution, the SQL query won't contain the padded input, causing shouldReturnEarly to incorrectly return true (missed detection).

Fix: Apply strings.TrimSpace after strings.ToLower for the user input before both the early-return check and the zen-internals detection call.

See: AikidoSec/firewall-java#298
