Adds dcl-liquidity.ts with concentrated liquidity position management
for the CLMM contract (dclv2.ref-labs.near).
All methods tested on NEAR mainnet:
- depositTokenToCLMM(): ft_transfer_call('Deposit') to store tokens
in CLMM internal balance before adding liquidity
- addLiquidity(): batch_add_liquidity direct call with pool_id,
amount_x/y, left_point, right_point, min_amount_x/y
- removeLiquidity(): remove_liquidity with lpt_id, amount, liquidate_type
- amount='0' harvests fees only (position stays open)
- amount=full closes position + claims principal
- getLiquidityPositions(): nft_tokens_for_owner enumeration to find
all LP NFT positions for an account
- openPosition(): convenience function combining storage registration,
token deposit, and batch_add_liquidity in a single transaction set
Fee tiers documented as 1% (fee=100) with point_delta=200 requiring
bin-aligned tick values (multiples of 200).
