Subject: [PATCH] fix: explain a closed directory and refused free/busy in the
 right words

With directory queries off on Stalwart 1.0, the free/busy list under the
attendees disappeared without a word. The share dialog explained every
`forbidden` from Principal/query with the 1.0 text: "only your groups
and people who have shared with you are listed", and a hint at
Stalwart's sharing settings. On 0.16 that refusal only means the role
lacks the permission, Principal/get then lists everyone, and the setting
has no effect over JMAP.

- When the server refuses free/busy for the user (`mayGetAvailability`
  false on the user's own principal, or a lookup refused with
  `forbidden`), one muted line says "Free/busy isn't available on this
  server". The block stays empty only when the server offers no
  free/busy at all.
- The share dialog keeps the 1.0 wording for Stalwart 1.0's own refusal
  ("The administrator has disabled directory queries.") and otherwise
  says "Your server doesn't let you browse its user directory.", still
  listing whoever Principal/get returned.
