The "notification settings" page previously advertised support for
mobile push notifications via checkboxes, even if the server hadn't
yet been registered for push notifications. This was a frequent
source of onboarding pain for new Zulip organizations.
We fix this by providing a clear warning and disabling the relevant
inputs on the settings pages.
Modified significantly by tabbott to correct some tricky logic errors
as well as some copy-paste bugs.
Fixes#10331.
This deduplicate code for the checkboxes which are dependent on other
parameters and it makes no sense changing them when that parameter is
false. For example, changing `message_content_in_email_notifications`
makes sense only when `enable_offline_email_notifications` is true.
Some labels like one for `translate_emoticons` which contains HTML
get escaped because of use of `{{ label }}` syntax, which escapes
the string for XSS security purpose but since labels aren't any
threat to any such security cases, we can use triple curly brackets
`{{{ label }}}` syntax.
Fixes: #9231.
(It is a preliminary change for deduplication of org settings template.)
This is done because of some settings like organization-settings
has ids which match the pattern of having a prefix `id_`
before the property name.
For those settings which don't have any prefix, there will be no
effect.
Here obsolete `t` in the label is removed since we do
label translations in JS files.
