fix #213: complete suicide and framerate presentation

Translate suicide response 0x004A as retail's successful self-kill notice. Port /framerate onto the authored SmartBox FPS element with live two-decimal FPS and DEG values, keep diagnostic window chrome independent, and synchronize command-driven settings without discarding panel drafts.

+The two-line template is portal string-table entry `0x0DCFFF73` in table
