ChuckandClaude Opus 5 4f24e2aa42 feat(web): show available memory in Tools diagnostics ...

System Diagnostics reported memory as used-percent plus used/total GB.
Neither distinguishes a healthy board from one about to fail, because
page cache counts as used and is reclaimable on demand -- a Pi can read
70% used and be fine, or read the same and be minutes from trouble.

MemAvailable is the kernel's own estimate of what a new allocation can
actually obtain, and it is the number that tracked the failure on a 1GB
Pi 3B+: healthy running sat above 500MB, and the crash came at 73MB. By
that point fork() was failing, so sshd could not spawn a session and
systemd could not respawn the display, while the kernel carried on
answering pings at 0% loss. Used-percent gave no warning at any point on
the way there; available memory fell steadily for hours.

/api/v3/system/status now returns memory_available_mb from
psutil.virtual_memory().available, and Tools renders it as its own tile,
coloured against the thresholds that failure implies: red under 150MB,
amber under 300MB, green above.

The existing memory tile is left alone -- used/total is still what you
want when sizing a workload; this answers the different question of how
much room is left right now.
