[GeorgeTsagk]

Description

Adds an itest edge-case where a tap channel is force closed immediately without any commitment updates.

Needs an LND update too, so blocked on lightningnetwork/lnd#10804
Based on #2133
Now also based on #2186 as we need the v2 deps bump

Summary of Changes

This pull request introduces a new integration test to validate the edge case of force-closing a tap channel immediately after funding. To support this, the PR includes critical updates to the auxiliary funding and sweeping logic, ensuring that commitment output allocations and BTC balances are correctly calculated to maintain consistency with on-chain commitment transactions.

Highlights

• New Integration Test: Added a new integration test case to verify that a tap channel can be force-closed immediately after funding without any prior asset movement.
• Auxiliary Funding Logic: Updated the initial BTC balance calculation in the funding controller to ensure commitment output ordering matches the real commitment transaction.
• Sweeper Refactoring: Refactored commitment output allocation logic to correctly handle exclusion proofs for real commitment transactions on-chain.
• Dependency Updates: Updated several project dependencies in go.mod and go.sum to ensure compatibility and stability.
