dunst: make the font size and width settings, defaulting to today's values (hq ADR 0262)

Browse Source 
The laptop's 242 DPI panel shows Inter 10 at less than half the workstation's size. The
defaults keep every machine's file byte for byte as it is; a machine sets its own.

## Settings
Two preferences have defaults in the definition (novox/hq ADR 0262). The mesh's layer, then a machine's,
overrides them, and the file is written with the value, never with a variable dunst reads.
| setting | default | what it is |
|---|---|---|
| `font-size` | 10 | the points of `font = Inter <size>`; 10 reads well on a screen of about 100 DPI, which is the workstations |
| `width` | 250 | the notification's width in pixels; a larger font needs a wider notification |
A machine with a denser screen sets both for itself, and the next push writes them:
mesh-controller.settings {module: "dunst", node: "<machine>", values: '{"font-size": 16, "width": 400}'}
`mesh-controller.settings {module: "dunst", node: "<machine>"}` shows each value and where it came from:
the default, the mesh, or the machine. dunst reads its file when it starts, and nothing in this module
tells a running dunst that the file changed: a new size shows at the next login, or after `dunstctl reload`.
## What it chose, and what it improves
The workstations' files differed: one had the notifications bottom-right, 15 % transparent and with
