Feat/upgradeable pools

[lastperson]

Closes: #233

[Copilot]

Pull request overview

This PR implements issue #233 by converting the Liquidity Pool contracts (and related components) to an upgradeable architecture using proxies and initializer-based setup, and updates deployment scripts/config/tests accordingly.

Changes:

• Refactors core pool contracts (LiquidityPool*, PublicLiquidityPool) and ERC4626Adapter to upgradeable patterns (initializers + ERC7201 storage).
• Updates deployment scripts and network configuration to deploy and reference TransparentUpgradeableProxy instances.
• Updates Hardhat tests (and Echidna harnesses) to deploy pools/adapters behind proxies and assert non-reinitializability.
