feat: Select token supports uppercase search & Support symbol search

[nlyrthiia]

Description of the Changes

When entering 'ETH', 'usdc' in the search box, the correct results cannot be obtained. After the modification, the uppercase can also be used to search for the correct results and the search for the symbol field has been increased. There is also a discussion about whether spaces should be included in the search. Referring to uniswap, both upper and lower case can be searched normally, spaces are not in the search field, and only symbols are retrieved.
