fix: Swap completion detection relies on a fragile timing assumption (#415)

Browse source 
Replace the try/catch on observing the transient 'Submitting…' button text with a
two-phase disabled→enabled check. The button gains the `disabled` attribute the
moment `swapping=true` and loses it when the swap finishes. By placing
`toBeEnabled({ timeout: 60_000 })` unconditionally after the try block, both
paths (fast RPC where disabled state cycles in <100 ms and slow RPC where it is
clearly observable) now wait for the actual ready state rather than falling
through to only a 2-second static guard.
