fix: duplicate dest assets visible in bridge page

[micaelae]

Description

Some tokens get displayed twice due to chainIds being in different formats, depending on data source. ERC20 tokens were also not being looked up correctly due to lowercased addresses.

Related issues

Fixes: #30765

Manual testing steps

1. Go to Bridge page
2. Check that there are no duplicate native tokens in src and destination asset picker
3. Try searching by symbol and verify that list gets updated with matching tokens
