Add a source list to the sidebar and lead with the Records tab

The sidebar now lists every source under the Sources item when it is
expanded, so entering a source takes one click instead of two. Bank
feeds sort first, then CSV sources, alphabetical within each group, and
a small icon marks which is which — the same config.simplefin test the
Import page uses.

Selecting a source lands on Records rather than Setup: the index route
under /sources/:name redirects there and Setup moved to an explicit
/setup path at the end of the tab strip. Setup is the rare job; Records
is the frequent one.
