GuestBook: Rental Host

Push notifications now work on device. The push entitlement was never actually applied to any build, which is why team notifications never arrived on hardware. A payment request built from a nightly rate is held until both stay dates are set. Before, a rate typed without dates billed the cleaning fee alone and the message read as a finished total. A generated Stripe or Square link is also dropped when the total changes, so it can no longer collect an old amount. Arrival and departure cards say whether the nights are still ahead or already spent. Readability and reach: deeper sub-line and accent colours so small text holds up on cream, drawn icons in place of typed characters, and the PIN pad, notification toggles, section headers and list rows now work from a keyboard and announce their state. Heads-up tiles centre when they fit and pack from the left when they wrap, and a long label no longer clips its own icon. Smaller install and update download.
