Fix approval popup: init listeners before early return, rename view, space buttons

The Allow/Deny buttons did nothing because approval.init(ctx) was
called after the early return for approval mode, so listeners were
never attached. Move it before the check.

Rename view from "approve" to "approve-site" to avoid ambiguity with
future transaction approval. Space Allow and Deny buttons apart with
justify-between to prevent misclicks.
