mici: add a refresh models button to the models panel (#2018)

models: add a refresh models button to mici, gate and show progress on both panels

Adds the refresh-models tile to the mici models panel (it was missing there),
factoring the sync-key trigger + in-progress check into refresh_model_list()
and refresh_in_progress() shared with the big UI.

On both UIs the refresh button is now gated on offroad + not-downloading +
not-refreshing (the manager runs offroad-only and its per-tick manifest fetch
sits above a blocking download loop, so a refresh queued in either state would
stick), and shows progress while the manager refetches: mici shows "fetching..."
on the tile, the big UI flips its button from REFRESH to "FETCHING..." to match
its FETCHING.../SELECT/CLEAR label style (as in the OSM panel), replacing the
old fire-and-forget popup.
