Add real deposit-wait progress to Bridge screen, reusing the swap timer UX

Tapping Swap on the Bridge screen previously gave zero feedback afterward -
the same countdown/success UX already used for swap execution didn't exist
here, so a user had no way to tell whether anything was happening. Moved
ExecutionTimerView (+ its layout) from feature-swap-impl to common, since it
was already fully self-contained (no swap-specific coupling, all its
resources already lived in common) - both features now share the one
component instead of duplicating it.

Wired into BridgeViewModel: after a swap is submitted, actively observe the
destination balance (walletInteractor.assetFlow) for a real increase within
a bounded window, showing the countdown while watching and Success only on
a confirmed balance delta - never a cosmetic timer that "completes"
regardless of whether funds arrived. If the window elapses without
confirmation, it says so plainly (may need manual 3-of-5 review) rather than
showing a false success or a false error.
