feat(statics): add testToken (SOL) to BitGoJS statics

Add testToken as a test-only SOL token to @bitgo/statics, including
the UnderlyingAsset enum entries, on-chain SPL token factory, and
OFC factory.

Changes:
- modules/statics/src/base.ts: add `tsol:testtoken` (test on-chain)
  and `sol:testtoken` (mainnet-style key for OFC reference) to the
  UnderlyingAsset enum
- modules/statics/src/coins/solTokens.ts: add tsolToken entry with
  UUID fcb25a47, mint So111...(Wrapped SOL placeholder), 9 decimals
- modules/statics/src/coins/ofcCoins.ts: add ofcsolToken entry with
  UUID 4b17b883, name ofc:sol:testtoken, 9 decimals

This is a dry-run/test token to validate the Linear ticket workflow.
The contract address is the well-known Wrapped SOL mint reused as a
placeholder — not a real deployment.
