Polish imports, types, tests, and server code

Various tidy-ups and type fixes across the repo:

- biome.json: add excludes for coverage and dist to file matcher.
- Normalize and reorder imports in multiple modules; export wallet provider classes from wallet index.
- Improve TypeScript typings and function signatures (viem Abi/WriteContractParameters, return types, more precise mock/spy types).
- Replace unused catch parameters with catch { } and add explicit radix (10) to Number.parseInt calls for correctness.
- Adjust tests to use stronger typings for mocks/spies (use never / ReturnType<typeof mock> where appropriate) and reorder test imports for consistency.
- Minor server/transport fixes: avoid unused req param, import/registration ordering, and streamable/http transport/import cleanup.
- Small fixes in ledger/cosmos modules (import ordering) and other minor refactors to satisfy linters/TypeScript.

These changes improve type safety, lint/test reliability, and code consistency.
