[KYUUBI #7403] Password with colon bug fixes

### Why are the changes needed?

If a password contains a colon, REST API does not pick up colons. Similarly, password string like `correctpassword:random-charachars` gets parsed as `correctpassword`.

### How was this patch tested?

Tested in local build, password with colon are getting parsed properly.

### Was this patch authored or co-authored using generative AI tooling?

Test Suite was helped by Cursor auto-complete.
