fix(devices): K200L status parser reads a fault's Yes, which the board wraps in <FONT color=#ff0000>

First live run on park-lab with the cover open reported "unexpected status page
(missing coverOpen, paperEnd, offline)" — exactly the three fault cells. The board
writes a fault as <FONT color=#ff0000>Yes</FONT> and a clear row as a bare padded
No; the parser accepted only tag-free cells. Cell text is now read with inner tags
stripped (row-anchored match). Tests pin the verbatim captured markup plus other
shapes. Live after the fix: degraded "cover open, paper out, printer off-line";
cover closed → ready.

Wiki: the markup on the K200L page; Periphery "not loaded after reboot" (unit never
enabled → `systemctl --user enable --now periphery`) as a §7a gotcha in the
provisioning runbook; log.
