`new_for_test` was `Self::new()`, and `new` loads the real settings file. So
every test ran against whatever the person running it had last set in the
application. It surfaced as `a_selection_past_the_limit_gets_no_grips`
failing on a machine where GRIPOBJLIMIT had been changed by hand: the test
expected the default limit and got 32767. On a clean checkout, and in CI, it
passes — which is the worst shape for this kind of bug.
Tests now start from `AppConfig::default()`.
That alone made things worse rather than better. The suite builds whole
applications and changes preferences on them, and `AppConfig::save` writes to
the real path, so a test run would have written *defaults* over the user's
file where before it wrote back roughly what it had read. `save` is now inert
under `cfg(test)`.
Both halves matter: the first makes the suite deterministic, the second makes
it harmless. This series adds around fifteen persisted settings, so every one
of them was another way for a developer's own configuration to turn the suite
red — or to be quietly overwritten by it.

**TEXTFILL marked the drawing modified.** It is an application preference —
it lives in a process global and is snapshotted into settings.json — but it
was missing from the list of names that persist, so setting it dirtied the
open drawing instead and never reached the settings file through that path.
**LTSCALE and CELTSCALE validated differently depending on the door.** The
standalone commands reject a value of zero or less, because a non-positive
linetype scale degenerates every dash pattern in the drawing. `SETVAR LTSCALE
-5` accepted it. A test drives both entry points for both variables and fails
on the SETVAR path without the fix.
**ISAVEBAK, SAVETIME and FILEASSOC were missing from the autocomplete
registry** although all three dispatch, so the command line never offered
them.
**`bg_color` and `paper_bg_color` were dead fields**, always written as `None`
and ignored on load since the model-space configuration superseded them.
Removing them is safe: the config is `#[serde(default)]` and ignores unknown
keys, so existing settings files simply stop carrying them.
One thing the survey flagged that turned out not to be a bug: on the Display
page the model background row hides itself outside Custom mode while the
paper and desk rows do not. That asymmetry is correct — the canvas mode
governs only the model background, and the other two apply in every mode.
