Translate English built from template literals in attributes

i18n-literals now flags a template literal in a UI attribute or prop when
there are words between its values: `Remove ${email}`, `${name} — shared by
${owner}`. It cannot be a catalogue key as written, so neither the key
exemption nor the sentence-shape test applies. A template that is only
punctuation around values, like `${name} (${size})`, is left alone.

The twelve it found are now keys with placeholders: the quota bar title,
the address menu's label, a folder's subfolder unread count, a recipient
chip's remove button, the contact editor's title, shared and available
calendars and address books, the date and time fields' labels, the
attachment title's fallback name, and the free/busy bar. The bar showed
the raw JMAP busyStatus ("confirmed") and now says Busy, Tentative or
Unavailable.

11 new keys in all nine catalogues. Remove {address}, Date, Time, Busy and
Tentative already existed.
