fix(rooms): "Rename for me" names in Ctrl+K, forward/share pickers and notifications (#336)

The personal room name (io.lotus.room_names) was only used by the
sidebar, header, intro and call bar; the quick switcher couldn't find a
room by it ("No match found") and showed the server name, as did the
forward/share pickers, toasts, OS notifications and reminders.

useRoomMeta gains useLocalRoomNames() / getLocalRoomName(); the quick
switcher matches both names and shows the personal one, the forward and
share pickers show and filter by it, and message/reminder notifications
use it for the room title.

Verified headless with general renamed to "Zebra Lounge": Ctrl+K "Zebra"
and "general" both list "Zebra Lounge"; the forward picker filtered by
"zebra" lists "Zebra Lounge".

Not covered here (follow-up): message-search result headers, the inbox
notifications page and the threads list still use the server name.
