Subject: [PATCH] fix: add WETH to uniswap token database

The Uniswap approve liquidity handler (zxappliquid.c) calls
tokenByTicker("WETH") to compute V2 pair addresses via CREATE2.
Without WETH in the token table, the firmware returns false before
any button prompt, causing "Signing cancelled by user" in tests.
