fix(hub): refresh directory list after adding/removing a shared root

Folders (unlike files) only ever arrive over MNP as part of a full
index_sync — the ongoing index_delta push has no `dirs` field at all
(daemon.py never puts one there for incremental updates) — so a directory
added or removed via the Electron-local add/remove flow never showed up
in the Videos/Music root pickers until the whole page was reloaded. The
merged Directories section made this easy to hit: add a shared folder,
then immediately try to pick it as a root, in the same visit. Both
actions now call the same onRefreshIndex a chat upload already uses to
pick up its own effect on the index.
