improvement(performance): add support for user profile in HDR analysis

This commit introduces two changes to enable user profile support in performance testing:

Set the HDR tag according to the stress command when using a user profile. Currently, only
standard operations (read and insert) are supported for user-profile-based stress commands.

The HDR tag for stress commands with a user profile is now written in lowercase. The tag
validation logic has been updated to perform a case-insensitive comparison.

(cherry picked from commit 2df90d9)
