Fix print.push_status parsing, and stop losing reports silently

Browse Source 
Pointed at a real H2C that was 20% into a job, `print_status()` returned
nothing at all. The printer was in fact pushing a full status object every
second; every one was arriving, failing to deserialize, and being dropped
invisibly by an `if let Ok(report) = ..` with no `else`.

That silence produced two confidently-wrong claims in our own comments,
both corrected here:

- `pushall`'s doc said whether v2 emits `push_status` unprompted was "an
  open question". It is not: v2 pushes a full 97-field object roughly once
  a second from the moment you subscribe, no trigger needed. There is no
  missing "other trigger" to hunt for.
- The "sequence gap" warning blamed the network for dropped v1 updates.
  Those updates were not dropped in transit - they failed to parse, so
  they never reached the counter, making the next one that did look like a
  skip. Confirmed: seq 57, 62, 64 and 69 all arrived. After the fix, zero
  gaps and zero parse failures across a 25s run against both printers.

Two concrete causes, both found with captured payloads:

- v1 trays carry `tray_temp`/`tray_time`; v2 trays carry
  `drying_temp`/`drying_time`. All four were required, so *every* v1 push
  carrying AMS data failed.
- A third tray shape existed that nothing modelled: an empty v2 slot sends
  `{"id": "2", "state": 0}`, which matched neither `EmptyTray` (it denies
  unknown fields, deliberately) nor `LoadedTray` (16 fields short).

A parse failure now reports itself, naming the printer, the sequence id and
the serde error. A report this process cannot parse is a defect in
`PrintReport`, and the only way to fix it is to be told which field.

`PrintReport` itself modelled 9 of 97 top-level fields, and none of them
were progress or temperature - it was built from a truncated example. It
now carries gcode_state, percent, layer counts, remaining time, nozzle/bed
temperatures, fan gears, wifi and HMS entries. `merge_from`'s two dozen
four-line blocks collapse to `newer.x.or(self.x.take())` one-liners: the
old shape made adding a field a three-place edit, and forgetting the merge
half produced a field that silently never survived a partial update.

Two scale traps documented where they bite: reported fan speeds are 0-15
gears, not percent and not the 0-255 PWM we send (`set_fan_speed(50)`
reads back as "7"); and v2 pins `sequence_id` to one value for minutes
while contents change, so it orders and identifies nothing there.

Two examples, and the distinction between them is the point. `live_reports`
is read-only and safe against a printer mid-job. `bambu_idle_checks`
writes, so it requires an explicit printer id and refuses to run unless
that printer reports `gcode_state: "IDLE"`.

Regression fixtures are verbatim captures off both printers, hardware
identifiers scrubbed - the only way to keep this from regressing without a
printer plugged in.

//! Does `PrintReport` actually parse what real printers really send?
//!
//! The fixtures in `tests/fixtures/` are verbatim `print.push_status`
//! payloads captured off real hardware on 2026-10-03 via
//! `cargo run --example live_reports` (hardware identifiers scrubbed):
//!
//! - `push_status_v1_p1p_idle.json` - a P1P on BambuMQTT v1, idle.
//! - `push_status_v2_h2c_printing.json` - an H2C on BambuMQTT v2, 13% into
//! a real job.
//!
//! These exist because the struct was originally built from a *truncated*
//! example payload, and the gap between that and reality turned out to be
//! the cause of two live misbehaviours (silently empty `print_status()`, and
//! bogus "sequence gap" warnings). A fixture is the only way to keep that
//! from regressing without a printer plugged in.
