Context
TokenSelector displays a static list of default tokens without an input filter for searching custom or imported tokens.
Why it matters
When custom Soroban tokens are added or when the token list grows, finding specific tokens becomes tedious.
Suggested approach
Add a search input inside TokenSelector with debounced filtering across symbol, name, and 56-char address.
