feat(render): name the active account in the buffer title

With two workspaces, the preamble summary read "Pearl - <view> ..." for both, so you couldn't tell from the title which account a buffer belonged to. It now reads "Pearl - <account> - <view> · <count> · <time>", pulling the account from the buffer's #+LINEAR-ACCOUNT. A legacy buffer with no account stamp drops the segment and reads as before.
