fix / extract positionRent from transaction balances for Orca CLMM

[mlguys]

Summary

Fixes #608 — Orca CLMM connector was reporting incorrect positionRent / positionRentRefunded values and incorrect baseFeeAmountCollected on close.

Related fix: #591 (same approach applied to Meteora, commit e9b15fb)

Key Changes

• Correct rent calculation on open — Previously only summed rent for 3 position accounts (~0.002 SOL), missing tick array initialization rent (~0.013 SOL each). Now extracts rent from the confirmed transaction's postBalances for ALL newly-created accounts (position mint + PDA + ATA + tick arrays).

• Correct rent refund on close — Extracts rent refund from the transaction's preBalances for closed position accounts. Tick arrays are shared resources and not closed, so their rent is correctly excluded.

• Correct fee calculation on close — Previously used collectFeesQuote() which reads position data BEFORE the updateFeesAndRewards instruction executes on-chain, returning stale/incorrect values. Now derives fees from actual balance changes: fees = totalReceived - liquidityRemoved.

• Refactored initializeTickArrays() — Now returns PublicKey[] of newly-created tick array accounts so their rent can be tracked.

Files Modified

• src/connectors/orca/clmm-routes/openPosition.ts — Rent from TX postBalances, token amounts from extractBalanceChangesAndFee()
• src/connectors/orca/clmm-routes/closePosition.ts — Rent refund from TX preBalances, fee derivation from actual balance changes
• test/connectors/orca/clmm-routes/openPosition.test.ts — Updated mocks for new getTransaction / extractBalanceChangesAndFee calls

[rapcmia]

• Setup with hummingbot development branch on source
• Setup with Helius nodeURL (free ver) and tested with {PYUSD, SOL}-USDC pair
• Successfully open and close LP positions
• Compared logs from recent gateway logs (archived files)
• Observed print rent-breakdown in addtiion to existing position rent summary
• Also added rent refund when closing position ok
• Tests on PYUSD-USDC returned 0 fees because no active occured from the time it was open to close
• Had SOL-USDC LP closed with some swaps happened while it was active:

Looks like position rent and refunds are now correct. However, the fee field only contains base fee, but not priority fees paid.

In addition to tx fees, it looks like the base and quote fees collected weren't exactly what the transaction returned (0.000002059 SOL and 0.000344 USDC)
