Subject: [PATCH] fix(statics): add LIQUID_STAKING feature to hypeevm staking
 tokens

Add CoinFeature.LIQUID_STAKING to hypeevm:hwhype (Hyperwave HYPE) and
hypeevm:khype (Kinetiq Staked HYPE). Without this flag, the backend
cannot identify these as liquid staking derivatives and fails to link
the HYPE debit with the hwHYPE/kHYPE credit during pending approval,
causing the wallet balance to appear doubled in the UI.

The OFC counterparts (ofchypeevm:hwhype, ofchypeevm:khype) inherit
the feature automatically via getFilteredFeatures in ofc.ts.

Also adds DEFAULT_FEATURES_EXCLUDE_SINGAPORE to hwhype for consistency
with khype, since both are staking products excluded from Singapore
custody.

Ticket: CECHO-739
