Martino Ferrari f00d161900 fix: row titles mean their mnemonics instead of drawing the underscore
Fifteen display strings in the two preference forms were written as GTK mnemonics -- `_Directory`,
`_Server`, `Multicast _group`, `_Theme` and the rest -- but the property that makes GTK read them was
never set, so GTK drew the underscore literally: `_Directory` in the row, not a D with a line under it.

Two switches are involved, FALSE by default in each case. `GtkLabel`/`GtkButton` take `use-underline`;
the rows take `AdwPreferencesRow:use-underline`, "whether an embedded underline in the title indicates a
mnemonic". The two buttons in the source form already set it (so their mnemonics worked and showed no
underscore); the thirteen rows did not. All thirteen now do.

The row classes that carry the property are not all related -- AdwEntryRow has its own, while AdwSpinRow,
AdwComboRow and AdwSwitchRow get it through AdwActionRow -- so the probe reads it by name on a GObject
(g_object_class_find_property, then g_object_get) rather than casting to one row type; a cast to a
`GtkWidget*` where the type is only forward-declared does not compile at all.

`_Cancel` and `_Connect` both claimed C in the same form, so Alt+C could only reach one of them: that
marker was unreachable, which is worse than absent because it is in the source to be trusted. `_Connect`
becomes `Conn_ect`, freeing C for Cancel.

[prefs-probe] reads the count (4/4) on the real widgets; check_ui validates the property against the GIR
for every object in every .ui file, inherited properties included.

The form a source is added or edited with: one dialog, two groups, eight rows.
A grid of labels and bare entries is what this was, and a grid is the wrong shape for it. Each row
here is a whole row — a title, a subtitle under it where the hint used to be a placeholder, and the
editing widget on the right — so the form reads the way every GNOME application's does, and the hints
survive being typed over (a placeholder does not: it disappears the moment there is a value, which is
exactly when a user may want to know what empty meant).
The action is in the header bar rather than a button row at the foot: it is what the dialog is *for*,
it is what the keyboard's Enter reaches, and its label says which mode the form is in — `Connect` for
a new host, `Save` for an existing configuration, which `source_dialog.cpp` sets.
Nothing here carries a value. The dialog is filled from the source being edited, or from the command
line for a new one, by the code that opens it.
