Templ ETH yield deployment — Aave V3 via session-anchored router

Description

Routes full idle Treasury ETH (0.047103135570621846 ETH) into Aave V3 aWETH via TempleAuthYieldRouter at 0x71223920d82EF1C7A949eefE36865065C0CCD49B. Context: Treasury holds idle native ETH following P#128 (WETH→ETH unwrap, you FOR'd). Per the productive-deployment policy (Aave USDC #150, Aave ETH #131, Aave ETH #140 — all FOR'd), idle native ETH should be deployed into productive Aave V3 aWETH positions. Non-custodial: aWETH credited to msg.sender (Treasury) via Aave's onBehalfOf semantics. Anti-MEV session anchoring preserved (per anti-frontrunning template). Bytecode pattern identical to #131/#140 FOR'd routers: WETH constant + AAVE_POOL constant + wrap/approve/supply path. Action: Treasury.execute(0x71223920d82EF1C7A949eefE36865065C0CCD49B, 0.047103135570621846 ETH, depositETH())
