feat(statics): exclude Singapore custody for COIN-7835 testnet tokens

Per legal/compliance review on COIN-7835 (Louis Cheung, Gaurav Pal),
the following six testnet tokens are capital-markets / stablecoin
products that BitGo Singapore cannot custody:

  tbaseeth:tusdl    USDL (BASE Sepolia)
  ttrx:tusdlt       USDLT (Tron Shasta)
  hteth:htusdl      USDL (Hoodi Sepolia)
  hteth:htusdlt     USDLT (Hoodi Sepolia)
  tpolygon:tusdl    USDL (Polygon Amoy)
  tpolygon:tusdlt   USDLT (Polygon Amoy)

Each token now uses the EXCLUDE_SINGAPORE feature preset so
CUSTODY_BITGO_SINGAPORE is removed from its features list.
