* fix(ui): let update and backup buttons fit their labels
The update dialog gives its two buttons a fixed 100 px width, and the
backup view puts its buttons in a fixed 200 px grid column, so longer
labels are cut off, for example "Only Chec", "Check and" and "Backup
to remote (WebD" in English. Use MinWidth="100" for the update buttons
and an Auto column with MinWidth="200" for the backup buttons: short
labels keep their current size and long ones fit.
The "Automatic update interval (minutes)" label of the subscription
window is cut off the same way between the switch and the interval
field, so let it wrap.
* fix(ui): show cut-off input hints as tooltips
The hints of the previous and next proxy remarks fields in the
subscription window and of the server and log filters are wider than
their fields, so their end is cut off and there is no way to read it.
Show the same text as a tooltip, as the custom config socks port field
of the subscription window already does.
* fix(ui): let dialog buttons and backup labels fit longer translations
The Confirm and Cancel buttons of the editing and settings windows,
and the Reset button of the hotkey window, have a fixed 100 px width,
and the backup view puts its labels in a fixed 300 px column.
Translations longer than the English text are cut off there: the
Russian "Подтвердить" reads "Подтверди", and "Резервное копирование
на удалённый сервер (WebDAV)" loses its end. Use MinWidth="100" for
these buttons, as the message box already does with MinWidth="90",
and an Auto label column with MinWidth="300".
