Add config to disable /feedback (#8909)

Some enterprises do not want their users to be able to `/feedback`.

/>

Adds to `config.toml`:

```toml
[feedback]
enabled = false
```

I've deliberately decided to:
1. leave other references to `/feedback` (e.g. in the interrupt message,
tips of the day) unchanged. I think we should continue to promote the
feature even if it is not usable currently.
2. leave the `/feedback` menu item selectable and display an error
saying it's disabled, rather than remove the menu item (which I believe
would raise more questions).

but happy to discuss these.

This will be followed by a change to requirements.toml that admins can
use to force the value of feedback.enabled.
