alpha: decode Clipper environmental events

Restrict ES40 live environmental decoding to Clipper. Validate frame bounds
and string-table masks, and separate fault bits from status context.
Report valid notifications even when no recognized fault bits are set,
so door-closed and supply-return notifications remain visible. A single
status snapshot does not establish a recovery transition.

Keep SMIR bit 0 and inverted halt/reset bits as raw context. During the
ES40 PSU cable test, bit 0 remained set after the individual PSU failure
indication cleared. Its polarity/latching is unverified, so do not call
it a current PSU failure. Use mask 0x14 for the remaining SMIR faults.
Decode only QW1 through QW7 as live environmental status, as documented
in the ES40 Service Guide, Tables D-20 and D-21.

Use plain door-status messages. Preserve unknown or truncated frames
in bounded raw dumps. Firmware console-log scanning is independent of
the live environmental handler.
