fix(wallet): testing the connection no longer wipes an unsaved typed URI

"Test connection" then "Save" removed the wallet. handleWalletTest re-rendered
the pane (refreshWalletPaneState) in its finally, which repopulates the form from
SAVED settings — empty for a URI you typed but hadn't saved — wiping the field.
The next Save then saw an empty field and took the "removed" branch.

Test must preserve what the user entered: refresh only the button state
(applyWalletControlState), not the whole form.

tests/wallet-test-preserves-input.test.mjs: a Test of an unsaved typed URI keeps
it in the field. Mutation-verified (restoring refreshWalletPaneState fails it).
