fix(tui): match plain absolute paths when resolving sidebar slot order

Source installs are stored as filesystem paths without a file:// prefix.
Basename matching previously applied only to file:// specs, so those
entries fell through to the historic 900. Absolute local paths now
match by basename, same as file:// checkouts.
