fix(mail): recount unread when the notmuch database commits

Accounts counted only at shell start and when the mail page opened, so the
drawer tile drifted behind the inbox for the rest of the session: it read 14
while notmuch and the waybar pill both said 16. The waybar pill never drifted
because waybar-mail.sh watches the database; the drawer had no watcher.

Accounts now runs its own inotifywait -m on the xapian directory (the
directory, because Xapian replaces files on commit) and refreshes 300ms after
a commit burst settles. The watcher respawns after 5s if it exits, since a
dead one reproduces the drift with no visible error.

This is the prerequisite for removing waybar: the drawer becomes the only
place the unread count is shown.
