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.

Summary
Adds WETH (Wrapped Ether) to the uniswap token database.
keepkeylib/eth/uniswap_tokens.jsonzxappliquid.cUniswap approve handler which callstokenByTicker(chain_id, "WETH", &WETH)test_sign_uni_approve_liquidity_ETHintegration test failsContext
The firmware's Uniswap liquidity contract handler references WETH by ticker to validate approve transactions for ETH/token liquidity pools. The token was missing from the Python test library's token database, causing the approve test to fail while add/remove liquidity tests (which don't reference WETH) passed.
