fix(ui): Esc cancels delete confirmation instead of confirming it

In the remove-wizard's confirming state, pressing Esc was reflexively
calling removeForwardsCmd — i.e. confirming deletion. The on-screen
help text said 'Esc: Cancel'. Reflexive Esc-to-cancel destroyed data.

Esc now sets confirming=false and resets the cursor; deletion
requires Enter on Yes. Non-confirming Esc behavior (exit wizard with
ClearScreen) is unchanged.

Three regression tests added in handlers_test.go.
