A mass-backup webhook that exceeded ~2 KB used to be silently
truncated by `desc = message[:MAX_EMBED_DESC]` with MAX_EMBED_DESC
set to 2048 — half of Discord's real description limit and far
below what a multi-VM backup digest produces. The trailing jobs
just vanished from the channel.
Bring the channel up to Discord's actual webhook contract:
* description limit raised to the real 4096-char cap
* if the body still doesn't fit, split it on line boundaries into
one embed per chunk so every backup entry is preserved
* keep title + fields on the first embed only; attach the footer
and timestamp to the last embed so the rendered card has the
normal head/tail framing even when split across many embeds
* enforce Discord's 6000-char-per-embed cap (title + description +
every field name+value) — only kicks in when many large fields
combine with a chunk already near the description ceiling
* batch up to 10 embeds per webhook POST (Discord's per-message
limit) and POST additional messages sequentially with a 0.4 s
gap so a >10-embed digest doesn't trip the 5/2 s webhook rate
limit
Verified with synthetic mass-backup payloads:
* 14 KB / 200 jobs → 4 embeds, 1 POST
* 60 KB / 60 lines → 15 embeds, 2 POSTs (10 + 5)

`get_disks_observation_counts` maps each serial's count to that
serial's "most recent" device_name (so renames like ata8 -> sdh keep
the badge attached). When several physical disks have passed through
the same kernel name across reboots — common with NVMe, the kernel
probes in a different order depending on which slots are populated —
disk_registry keeps a row per (device_name, serial) seen and the
"most recent" device_name for a serial can now be in use by an
entirely different disk.
Concrete case from the wild: serial 211716800490 was nvme0n1 during
the previous boot and earned a real I/O observation. After removing
four of five NVMes, the surviving disk (serial 243332800236) booted
into nvme0n1. The badge layer mirrored 211716800490's count onto
nvme0n1 — which is now a different physical disk — and showed
"1 obs." on the wrong drive, while the modal (which scopes by the
current (device_name, serial) registry row) found nothing and
rendered an empty history.
Only mirror a serial's count onto its device_name when that
device_name is currently owned by the same serial, determined from
the freshest disk_registry row. The serial-keyed entry stays
unconditional so observations remain reachable when the disk is
re-plugged under another device name.

The v1.2.0 binary lingered in the repo after later releases. Remove
it so AppImage/ holds only the current shipping artefact.

The tracked binary still pointed at the build made before the
last two fixes landed (resolution_reason persistence in
health_persistence and disk-temp breakdown alignment in
storage-overview). Re-build the AppImage so the GitHub-published
binary matches what is actually running on the deploy targets.
