Two realmlist deviations say why they differ (#2968)

`docs/DEVIATIONS.md` never said why the login screen has a realmlist control: the reason sat in a test comment, and the list leaves tests out. It is now a `Deviation:` on the control, in `AccountLoginRealmlist.xml`. The host-name port's reason, "everyday use", said nothing, so it now names the case and why it's safe: an address 1.12.1 can dial means the same here.

 - `OpenBackpack` opens every equipped bag, not only the backpack, because that way the vendor and mailbox windows that call it (MerchantFrame.lua:35, MailFrame.lua:39) bring up every bag to sell or mail from. The was-open memory is keyed by bag id: `ContainerFrame1..12` are recycled across bags. The stock `CloseAllBags` (ContainerFrame.lua:702-707) runs unchanged: it calls this `CloseBackpack`, then closes bags 1 and up.

 - The stock FCF\_ChatTabFadeFinished (FloatingChatFrame.lua:989-992) nils oldAlpha even under a live hover, so leaving and re-entering within CHAT\_FRAME\_FADE\_TIME (a flick to the scroll buttons, outside the hover box, does it) stops the plate fading in (l.873) for the rest of the session; this keeps oldAlpha while hover is set because the stock one nils it even under a live hover.

The stock handler runs first, unchanged, on the this/event/arg1 already set for the dispatch. ([`assets/ui/FrameXMLFixes.xml:20`](../crates/benilla-app/assets/ui/FrameXMLFixes.xml#L20))
