Replace the FIRMA/XECX redeem slider with Agora-style 25%/50%/75%/Max
qty buttons plus a typed input, add an XEC vs AlpDex redeem switch with
size-aware rates and Best deal, and settle AlpDex redeems from a
confirmation modal on the redeem page instead of navigating to AlpSwap.
AlpDex confirm signs the settle template already fetched for that quote.
