Stable v2.8.14

Per-package email service on/off. Each hosting package can enable or disable the whole mail service. The toggle lives in the Package editor → Email tab and is now clearly labelled "Email service". Turning it off blocks mailbox and forwarder creation for customers on that package (SMTP/IMAP) and hides the Email menu for them — the entire mail service is disabled for the package. (The capability already existed and was fully enforced; this release makes it findable and documents it.)
