fix: entry natural width causes scrollbars in STT Engines and Wakeword (v2.03.38)

Gtk.Entry reports its placeholder text width as natural width. Without
set_width_chars(1), entries can't shrink below that, so pages with long
placeholders (URL fields, keyword rows) ended up wider than the dialog.

Added set_width_chars(1) to _entry(), _url_field(), ModelPicker,
_kw_shortcut_row, and _sound_field. Also added set_max_width_chars(50)
to the stt_result wrapping label for the same reason.

+### Fixed
+- **STT Engines and Wakeword no longer have horizontal scrollbars.** Root
+  cause: `Gtk.Entry` widgets compute natural width from placeholder text
+  (e.g. `"http://localhost:8010/v1  ·  realtime: http://localhost:8006/v1"`
+  ≈ 500 px). Without `set_width_chars(1)` the entry cannot shrink below its
+  natural width even when placed in an expanding container. Added
+  `set_width_chars(1)` to all entry-creating helpers: `_entry()`, `_url_field()`,
+  `ModelPicker`, `_kw_shortcut_row`, and `_sound_field`. Also added
+  `set_max_width_chars(50)` to the `stt_result` wrapping label.
