fix: always name a swap's output token, by address when no symbol is known (closes #346)

The Token Out line was pushed only when a symbol was known, so a swap to a token absent from the bundled list showed a Min. received figure with no statement of which token was being received. It now falls back to the address, mirroring the Token In precedent in the same file. Composes with the unknown-scale refusal from #340: the address names the token while the figure declares its scale unknown. Native ETH out, ETH out via UNWRAP_WETH and bundled tokens render exactly as before.

+- 2026-08-23: A swap always names its output token
+  ([#346](https://git.eeqj.de/sneak/AutistMask/issues/346)). The `Token Out`
+  detail line in `src/shared/uniswap.js` was pushed only when a symbol was
+  known, so a swap whose output token is absent from the bundled list — every
+  newly listed token — showed a `Min. received` figure with nothing saying what
+  was being received. The line is now keyed on the token's address and falls
+  back to it when there is no symbol, exactly as the `Token In` line already
+  did. It composes with the unknown-scale refusal from
+  [#340](https://git.eeqj.de/sneak/AutistMask/issues/340): the address says
+  which token, the base-unit figure says how much and states that the scale is
+  unknown.
