Orca: baseFeeCollected incorrectly includes position rent, positionRent values are wrong

[fengtality]

Summary

The Orca CLMM close-position endpoint returns incorrect values for:

1. baseFeeAmountCollected - incorrectly includes position rent refund
2. positionRentRefunded - shows ~0.002 SOL but actual rent paid/refunded is much higher

Root Cause

1. baseFeeAmountCollected: Uses collectFeesQuote() which calculates fees based on position data BEFORE the updateFeesAndRewards instruction executes on-chain. The returned value includes rent refund instead of actual fees.

2. positionRentRefunded: Only calculates rent for position mint, position data, and position ATA accounts (~0.002 SOL total), but misses other rent components. Actual position rent paid on open is ~0.015 SOL.

Example Transactions

Open Position

• TX: https://solscan.io/tx/nfzR3Q36Aax2VjLpNn6Hnnq7c6TMbMGJ8eZ15B1dU74DBmW29adi9YhkoDEPGTRPgYRtfgPD8uDQVy5nz2iX1Zi
• Actual position rent paid: ~0.0151156 SOL
• API reported positionRent: 0.00203928 SOL

Close Position

• TX: https://solscan.io/tx/2HhHE8pVcJZtruJ91T7DRDWfXLeiHTH7GxYmv1LYPK575sdUyyqjNkobCBVw31Uh5fH4iKY43WtdevaWxrdPzTDc
• Actual position rent refunded: ~0.005 SOL (currently included in baseFeeCollected)
• API reported positionRentRefunded: 0.00203928 SOL
• baseFeeAmountCollected: Incorrectly includes the rent refund instead of actual fees

Expected Behavior

1. baseFeeAmountCollected should reflect actual trading fees collected, not rent
2. positionRent (on open) should reflect all rent paid including tick arrays and other accounts
3. positionRentRefunded (on close) should reflect actual rent returned

Suggested Fix

1. Use extractBalanceChangesAndFee() to get actual token balance changes from confirmed transaction
2. Calculate fees as: totalReceived - liquidityRemoved
3. Investigate what accounts contribute to the full position rent (~0.015 SOL) and update rent calculation accordingly
