feat: replace erc1538 naming to diamond proxy naming

[gfournieriExec]

Migration steps:

• Migrate src files (minimal changes)
• Modify receive and fallback behavior in Diamond.sol
• Rename all 1538 to 2535 in contracts and rename Module to Facet in contracts names
• Update all facets to use namespaces app storage.
• Remove ENSIntegration modules/functions
• Update docs (soldoc, diagrams, ...)
• Add unit tests for Diamond.sol

Pull Request Overview

This PR migrates the codebase from ERC1538 naming conventions to Diamond proxy (ERC2535) naming conventions. The migration updates contract references, module names, configuration keys, and deployment scripts to reflect the transition from "modules/delegates" to "facets" and from "ERC1538Proxy" to "DiamondProxy".

• Renames all contract modules from "Delegate" to "Facet" (e.g., IexecMaintenanceDelegate → IexecMaintenanceFacet)
• Updates configuration keys from ERC1538Proxy to DiamondProxy while maintaining backward compatibility
• Migrates base contracts from DelegateBase to FacetBase

Comments suppressed due to low confidence (3)

test/utils/hardhat-fixture-deployer.ts:62

• The deployment name 'Diamond' is inconsistent with the variable name 'newProxyAddress' and the log message 'DiamondProxy'. Consider using 'DiamondProxy' as the deployment name for consistency.

        const newProxyAddress = (await deployments.get('Diamond')).address;

scripts/set-callback-gas.ts:15

• The deployment name 'Diamond' is inconsistent with the variable name 'diamondProxyAddress'. Consider using 'DiamondProxy' as the deployment name for consistency throughout the codebase.

    const diamondProxyAddress = (await deployments.get('Diamond')).address;

deploy/1_deploy-ens.ts:29

• The deployment name 'Diamond' is inconsistent with the variable name 'diamondProxyAddress'. Consider using 'DiamondProxy' as the deployment name for consistency with other parts of the codebase.

    const diamondProxyAddress = (await deployments.get('Diamond')).address;

Isn’t it a facet as well?
